Convenient and efficient total synthesis method for icaritin and derivatives of icaritin

The invention belongs to the field of natural medicine synthesis and particularly relates to a convenient and efficient total synthesis method for icaritin and derivatives of icaritin. The specific technical scheme is as follows: 2'-hydroxyacetophenone and benzaldehyde are used as raw materials, firstly, isopentene groups are introduced in aromatic rings of raw materials under the catalysis of anorganic polyacid metal ion complex, a flavonol framework is constructed under mild and green conditions, and an isopentenyl flavone compound comprising the icaritin and derivatives of icaritin is further synthesized. The method effectively overcomes the limitation of poor substrate solubility and poor regioselectivity when flavone is constructed firstly and then isopentene groups are introduced, the problems of frequent introduction and removal of protecting groups in a conventional isopentenylation method are solved, and the synthesis route is greatly simplified; and meanwhile, the problems of complex products and more byproducts in an isopentene group rearrangement method are solved. The total synthesis method provided by the invention is mild in condition, convenient to operate, high intotal yield and suitable for mass production of the isopentenyl flavone compound.

Method of obtaining complex acidic salts of divalent metals and dicarboxylic acids

A method of obtaining a complex acidic salt of a divalent metal and a dicarboxylic acid includes heating water in a reactor; adding a dicarboxylic acid to the heated water; stirring the water to dissolve the dicarboxylic acid in the heated water to produce a solution or a suspension of the dicarboxylic acid in the heated water; adding MeO to the solution or the suspension, where Me is a divalent metal; continuing the stirring of the solution or suspension until formation of the complex acidic salt Me(AcH)2.nH2O begins, where Ac is an anion of the dicarboxylic acid, and n=0-8; cooling the complex acidic salt to below a temperature of crystallization; sedimenting the complex acidic salt; filtering the complex acidic salt to remove water from the complex acidic salt; and drying the complex acidic salt.

CARBOXYLATE ACIDIFICATION

The present invention pertains to a method for preparing a carboxylic acid by acidification of a liquid feed comprising a carboxylate salt, which method comprises the steps of - providing a liquid feed comprising magnesium carboxylate; - providing a gas feed comprising gaseous hydrogen chloride; and - acidifying the carboxylate to carboxylic acid by bringing the liquid feed into contact with the gas feed, thereby forming a liquid effluent comprising carboxylic acid and magnesium chloride, wherein the gas feed comprising gaseous hydrogen chloride is derived from a thermal decomposition step wherein an aqueous liquid comprising magnesium chloride is subjected to a temperature of at least 300 °C, thereby decomposing magnesium chloride into magnesium oxide and hydrogen chloride, thus obtaining a solid comprising magnesium oxide and a gas comprising gaseous hydrogen chloride.
