    What is the chemical structure of -4-Ethyl-4-hydroxy-10-nitro-1H-pyrano [3 ', 4': 6,7] indolizino [1,2-b] quinoline-3,14 (4H, 12H) -dione?
    The chemical structure of (4S) -4-ethyl-4-hydroxy-10-nitro-1H-pyrano [3 ', 4': 6,7] indolicino [1,2-b] quinoline-3,14 (4H, 12H) -dione is formed by connecting many atoms in a specific way. This structure contains a core structure for the fusing of a pyran ring and an indolicino-quinoline ring.
    Looking at its structure, there are ethyl and hydroxyl at the 4th position, nitro at the 10th position, and a carbonyl at the 3rd and 14th positions, respectively, corresponding to the structural characteristics of diketones. This specific chemical structure gives the compound unique physical and chemical properties. The fusing method of its ring system, the position and type of substituents have significant effects on its reactivity, stability and biological activity. For example, the presence of nitro groups can affect the distribution of electron clouds, thereby changing the polarity and chemical reactivity of molecules; hydroxyl groups can participate in the formation of hydrogen bonds, affecting the solubility and intermolecular interactions of compounds; ethyl groups contribute to the spatial structure and lipophilicity of molecules. Atoms and groups cooperate with each other to form this complex and delicate chemical structure.
    What are the physical properties of (4S) -4-Ethyl-4-hydroxy-10-nitro-1H-pyrano [3 ', 4': 6,7] indolizino [1,2-b] quinoline-3,14 (4H, 12H) -dione?
    (4S) -4-ethyl-4-hydroxy-10-nitro-1H-pyrano [3 ', 4': 6,7] indolicino [1,2-b] quinoline-3,14 (4H, 12H) -dione is a complex organic compound. This substance may be solid at room temperature, and its molecules have multiple cyclic structures and polar groups, resulting in strong intermolecular forces. Melting point or higher, because more energy is required to overcome intermolecular forces.
    In terms of solubility, it contains hydroxyl groups and diketone groups, and has a certain polarity. In polar solvents (such as water and alcohols), it may have a certain solubility, but the overall structure of the molecule is complex and large, and the solubility may be limited; in non-polar solvents (such as alkanes), the solubility may be extremely low.
    In terms of stability, 10-nitro groups make it chemically active. Nitro is a strong electron-absorbing group, which can affect the electron cloud density of surrounding chemical bonds, causing it to be prone to nucleophilic substitution or reduction reactions. In case of reducing agents, nitro groups may be reduced to other groups such as amino groups; under certain conditions, hydroxyl groups may participate in esterification, dehydration and other reactions, and diketone groups can also participate in many organic reactions, such as nucleophilic addition.
    Spectral properties, in the infrared spectrum, the hydroxyl group has a characteristic stretching vibration peak in the range of 3200-3600 cm3; the carbonyl group has a strong absorption peak based on 1600-1800 cm3, which characterizes the structure of diketones; the nitro group also has a specific absorption peak. In NMR spectroscopy, hydrogen and carbon atoms in different chemical environments exhibit specific chemical shifts according to their chemical environments, which help to determine the molecular structure and the connection mode of groups.
    What are the synthesis methods of (4S) -4-Ethyl-4-hydroxy-10-nitro-1H-pyrano [3 ', 4': 6,7] indolizino [1,2-b] quinoline-3,14 (4H, 12H) -dione?
    The synthesis method of (4S) -4-ethyl-4-hydroxy-10-nitro-1H-pyrano [3 ', 4': 6,7] indolo [1,2-b] quinoline-3,14 (4H, 12H) -dione is rarely described in detail in ancient books, but one or two can be deduced according to the principle of organic synthesis.
    To form this compound, the basic structure of pyrano-indolo-quinoline can be constructed first. Or by re-cyclization reaction, such as using suitable substrates containing alkenyl, carbonyl and nitrogen heterocycles, under the catalysis of acid, base or metal, through intramolecular cyclization, the shape of its thick ring can be initially determined. < Br >
    Its 4-ethyl-4-hydroxyl moiety may be introduced after the initial formation of the structure. The addition of ethyl groups can be obtained by the reaction of halogenated ethane with metal-organic reagents (such as Grignard reagents), so that the ethyl group is connected to the target check point. The formation of hydroxyl groups can be achieved by oxidation reaction, or the corresponding alcohol precursor can be oxidized, or the unsaturated bond can be introduced into the hydroxyl group through hydration reaction.
    As for the placement of 10-nitro groups, it depends on the molecular environment. In the nitrification reaction, a mixed acid system of nitric acid and sulfuric acid is often used to replace the nitro group in the appropriate position of the aromatic ring. However, it is necessary to pay attention to the order of protection and de-protection of other sensitive groups of the substrate to avoid reaction disorder and impurity of the product.
    During the whole process of synthesis, it is necessary to fine-tune the reaction conditions, such as temperature, solvent, and the proportion of reactants.
