What is the chemical structure of (R) -1,2,3,4-tetrahydro-6,7-dimethoxy-1-veratrol isoquinoline hydrochloride?
The chemical structure of (R) -1,2,3,4-tetrahydro-6,7-diethoxy-1-naphthyl isoquinoline anhydride is an important research object in the field of organic chemistry. Its structure is composed of several key parts.
The core structure of this compound contains a naphthalene ring and an isoquinoline ring. The naphthalene ring has a conjugated double bond system, which imparts certain stability and special electronic properties to the molecule. The isoquinoline ring is also a nitrogen-containing heterocycle, which adds unique chemical activity and electron distribution characteristics to the structure. The two are connected to form a complex and functional basic skeleton.
On one side of the naphthalene ring, diethoxy groups are connected at positions 6 and 7. The ethoxy group is an electron supplier group, which can affect the density distribution of molecular electron clouds, and then change its physical and chemical properties, such as molecular polarity, solubility and reactivity.
On the other side, there is a formyl isoquinoline anhydride structure attached to the 1 position. Formalyl is an aldehyde derivative, which imparts electrophilicity to molecules and can participate in a variety of nucleophilic addition reactions. The isoquinoline anhydride part plays a key role in many organic synthesis reactions due to the high reactivity of anhydride groups. It can undergo hydrolysis, alcoholysis, aminolysis and other reactions, resulting in the derivation of many functional compounds.
From a comprehensive perspective, the chemical structure of (R) -1,2,3,4-tetrahydro-6,7-diethoxy-1-naphthoyl isoquinoline anhydride fuses multiple special groups, and the interaction of each part creates unique chemical properties and reactivity. It has potential application value in the fields of organic synthesis chemistry, medicinal chemistry, etc., such as as the synthesis of specific active pharmaceutical intermediates, or the development of new organic functional materials.
What are the physical properties of (R) -1,2,3,4-tetrahydro-6,7-dimethoxy-1-veratrol isoquinoline hydrochloride?
(R) -1,2,3,4-tetrahydro-6,7-diethoxy-1-naphthoyl isobutyrate naphthyl ester, which is an organic compound. Its physical properties are as follows:
Looking at its properties, it may be a crystalline powder under normal conditions. Due to the fact that many organic compounds of the same type containing naphthalene rings and ester groups are mostly in this state, due to the interaction between molecules, such as van der Waals force, hydrogen bonds, etc., the molecules are arranged in an orderly manner, and then a crystalline structure is formed.
Considering the melting point, in view of the presence of naphthalene rings in the structure of the compound, the naphthalene ring has a high conjugate system, which enhances the intermolecular force, so it is speculated that its melting point is relatively high. However, the specific value will change due to the influence of the substituent group. The introduction of ethoxy and ester groups may change the distance between molecules and the direction of the force, and the melting point fluctuates within a certain range.
In terms of solubility, according to the principle of similarity dissolution, the compound contains a hydrophobic group such as a naphthalene ring, and at the same time contains polar parts such as ethoxy and ester groups. Therefore, in organic solvents, such as ethanol, chloroform, etc., it may have certain solubility, because its polar parts can form intermolecular forces with organic solvent molecules; while in water, the solubility may not be good. After all, the overall hydrophobicity is dominant. Water is a strong polar solvent and interacts weakly with hydrophobic naphthalene rings. In terms of volatility, due to the relatively large size of the molecule and the interaction of various groups, a relatively stable structure is formed, so the volatility is weak and it is not easy to directly convert from liquid or solid to gaseous and escape.
What is the synthesis method of (R) -1,2,3,4-tetrahydro-6,7-dimethoxy-1-veratrol isoquinoline hydrochloride?
The synthesis of (R) -1,2,3,4-tetrahydro-6,7-diethoxy-1-naphthyl isobutyrate lactone is a key content in the field of organic synthesis. The synthesis of this compound can be carried out according to the following steps:
In the selection of starting materials, naphthalene compounds with specific substituents are often selected as cornerstones. For example, naphthalene derivatives with suitable substitution check points can be selected for subsequent introduction of ethoxy groups and other functional groups.
In the step of introducing ethoxy groups, it can be achieved by the Williamson ether synthesis method. Naphthalene derivatives and ethanol were alkylated with halogenated ethane under alkaline conditions, which promoted the successful integration of ethoxy groups into the 6 and 7 positions of the naphthalene ring. In this process, the selection of bases is very important. Inorganic bases such as potassium carbonate are commonly used to react in suitable organic solvents such as N, N-dimethylformamide (DMF). After heating and refluxing, the reaction yield can be effectively improved.
In the construction stage of lactone structure, the formyl group is first introduced at the 1 position of the naphthalene ring, which can be achieved by the Vilsmeier-Haack reaction. Using N, N-dimethylformamide and phosphorus oxychloride to react with naphthalene derivatives to generate 1-formylnaphthalene derivatives. Then, the isobutyric acid fragment is introduced, and the 1-formylnaphthalene derivative is condensed with isobutyric acid through a suitable condensation reaction, such as in the presence of a dehydrating agent, and then the loop is closed to form a lactone structure.
Monitoring of the reaction process is also a key link. The reaction can be tracked by thin-layer chromatography (TLC) to observe the disappearance of the raw material point and the formation of the product point, so as to judge the reaction progress. After the reaction, the product needs to be separated and purified, and column chromatography is often used to achieve effective separation of the product and impurities with suitable eluents, and finally obtain high-purity (R) -1,2,3,4-tetrahydro-6,7-diethoxy-1-naphthoyl isobutyrate lactone.
