The synthesis of 1- (3,4-dimethylacetyl) -6,7-dimethylacetyl isocoumarin is an important research topic in the field of chemical synthesis. The following are several common synthesis methods described in detail by Ru:
First, the synthesis path using phenolic compounds as starting materials. Select specific phenols, such as phenol derivatives with suitable substituents, and make them acylate with acylating reagents containing dimethylacetyl structures under the action of suitable catalysts. Commonly used catalysts, such as Lewis acid, such as aluminum trichloride, etc. This catalyst can effectively promote the reaction of phenolic hydroxyl groups with acylating reagents to form key intermediates. Subsequently, the intermediate product is cyclized within the molecule to form the core structure of isocoumarin. The conditions of this cyclization reaction are quite critical, and factors such as temperature, reaction time and solvent need to be precisely controlled to achieve the ideal reaction yield and selectivity.
Second, based on the synthesis strategy of o-halobenzoic acid derivatives. The o-halobenzoic acid derivative undergoes nucleophilic substitution with organometallic reagents containing dimethylacetyl groups, such as Grignard reagent or lithium reagent. During the reaction, the activity of the organometallic reagent, the type of halogen atom, and the polarity of the reaction solvent all have a significant impact on the reaction process. After the nucleophilic substitution is completed, the obtained product undergoes further molecular ring reactions to construct the skeleton of isocoumarin. In this process, it may be necessary to introduce an appropriate oxidizing agent or reducing agent to adjust the oxidation state of the reaction intermediate and promote the smooth progress of the cyclization reaction.
Third, the synthesis method using transition metal catalysis. Transition metals, such as palladium and copper, are used as catalysts to catalyze the coupling reaction of alkenyl halides or alkenyl borates containing dimethylacetyl groups with ortho-substituted benzaldehyde derivatives. The ligands of transition metal catalysts play a decisive role in the selectivity and activity of the reaction. Reasonable selection of ligands can achieve the synthesis of regioselectivity and stereoselectivity. The coupling product is cyclized and modified to produce the target product 1- (3,4-dimethylacetyl) -6,7-dimethylacetyl isocoumarin.
The above synthesis methods have their own advantages and disadvantages. In practical application, the most suitable synthesis path should be comprehensively considered and selected according to the specific experimental conditions, availability of raw materials and purity requirements of the target product.

3,4-Dimethoxybenzyl and 6,7-dimethoxyisocoumarin are both organic compounds, which are very important in the field of chemical synthesis and medical research. The following is a detailed description of their physical and chemical properties:
###3,4-dimethoxybenzyl
- ** Physical properties **: Under normal circumstances, this substance is mostly colorless to light yellow liquid, with a certain volatility, and can be slowly volatilized in the air. Its smell is weak and has a special organic smell. It is insoluble in water, but it can be miscible with most organic solvents, such as ethanol, ether, chloroform, etc., in any ratio. Due to its relatively small molecular polarity, it is difficult to form an effective interaction with water molecules, so it is difficult to dissolve in water; and it can be well miscible with organic solvents due to the similar principle of miscibility. Melting point and boiling point vary slightly according to the specific structure. Generally speaking, the boiling point is in a relatively high temperature range, about 200-300 ° C. Due to the presence of van der Waals forces between molecules, more energy is required to make it boil.
- ** Chemical properties **: The benzyl ring in the benzyl part of the molecule is aromatic and can undergo electrophilic substitution reactions, such as halogenation, nitrification, sulfonation, etc. Due to the high density of the electron cloud of the benzene ring, it is attractive to electrophilic reagents. Its methoxy group is the power supply group, which can enhance the electron cloud density of the benzene ring, making the electrophilic substitution reaction more likely to occur. At the same time, benzyl carbon-hydrogen bonds can be oxidized under specific conditions to generate corresponding alcohols, aldons or carboxylic acids. In addition, when benzyl is connected to other functional groups, substitution, elimination and other reactions can occur, showing a variety of chemical activities.
###6,7-dimethoxyisocoumarin
- ** Physical properties **: Usually white to light yellow crystalline powder with fine appearance. Compared with 3,4-dimethoxybenzyl, it is less volatile due to strong interactions between molecules, such as hydrogen bonds and van der Waals forces. The melting point is relatively high, mostly between 100 and 200 ° C. Due to the large intermolecular force, more energy is required to destroy the lattice and melt. It is also insoluble in water and easily soluble in organic solvents, such as acetone and dichloromethane. Although there are oxygen atoms in the molecular structure, the overall polarity is not enough to be well miscible with water, but it is compatible with organic solvents.
- ** Chemical properties **: The structure of isocoumarin gives it many unique chemical properties. The lactone ring part has a certain reactivity, and under alkaline conditions, a ring-opening reaction can occur to generate corresponding carboxylate and alcohol. The methoxy group on the ring can affect the distribution of its electron cloud, which has an effect on the reactivity of the benzene ring and the lactone ring. For example, in the electrophilic substitution reaction, the methoxy group can guide the substituent to a specific position in the benzene ring. In addition, the substance may undergo isomerization or decomposition reactions under light, heat and other conditions, and its stability is significantly affected by environmental factors.

The synthesis technique is complicated and simple, and the price of the raw materials used is also related to its price. For refined products, the synthesis requires exquisite methods and expensive materials, so the price is high; and for those who are inferior, the materials and methods used are slightly simpler, and the price is slightly reduced. In addition to the supply and demand of the market, if there are many people seeking and there are few supply, the price will increase; on the contrary, if the supply exceeds the demand, the price will be depressed.
It is to know the price of 1- (3,4-dimethoxybenzyl) -6,7-dimethoxybenzyl isoflavones in the market. When the supply and demand of the market are carefully inspected, and the dealers are consulted, a more accurate number can be obtained. Today, it can only be said that the price is between tens of gold and hundreds of gold per gram.

The safety and toxicity of 3,4-dimethylcarbamoyl and 6,7-dimethoxy isoflavones are related to people's health and cannot be ignored.
Let's talk about 3,4-dimethylcarbamoyl first, which is an organic compound. Among its molecular structure, specific chemical groups endow it with unique chemical properties. In the fields of industry and scientific research, there are applications. However, looking at its safety, if it is used in production and use, improper protection, direct contact with personnel, or inhalation through the respiratory tract, it can endanger health. According to past experiments and cases, a small amount of exposure may cause skin itching, redness and swelling, which is the initial reaction of the body; if long-term and large-scale exposure, it may damage the nervous system, cause delayed movement, cognitive impairment and other diseases, because it can interfere with the normal transmission of neurotransmitters. As for toxicity, it can be chemically reacted to generate harmful derivatives, which remain in the environment and harm the ecology. If this harmful substance is contained in the soil, it may cause abnormal plant growth, affecting crop yield and quality.
Let's talk about 6,7-dimethoxy isoflavones, which are flavonoids that are widely present in the plant kingdom. Talking about safety, moderate intake may be beneficial to the human body, such as regulating endocrine, relieving menopausal symptoms in women, or having an effect. Because its structure is similar to human estrogen, it can bind to estrogen receptors and exert weak estrogen activity. However, if excessive intake, it may cause endocrine disorders. Animal experiments have shown that long-term high-dose feeding of feed containing this substance may cause abnormalities in the animal reproductive system and decreased reproductive capacity. In terms of its toxicity, although it occurs naturally, if impurities are not removed or toxic impurities are introduced during the extraction and preparation process. And in the environment, its degradation products may affect the structure of microbial communities and disrupt ecological balance.
Therefore, the safety and toxicity of the two need to be treated strictly. The production, use and intake should follow scientific norms to prevent problems before they occur, so as to ensure life, health and ecological safety.
