Description
Technical Field
The invention relates to the fields of organic synthesis, efficient utilization of biomass resources, fine chemical industry, medicines, daily cosmetics and the like, relates to a preparation method of a biomass-based pyranoside derivative, and in particular relates to a method for obtaining the pyranoside derivative by taking carbohydrate and glycerol as raw materials through continuous multi-step serial reaction.
Background
The C-glycoside has excellent bioactivity, better acid resistance and enzyme catalytic hydrolysis performance, and important application in the industries of organic synthesis, biological medicine and daily cosmetics. However, the methods of C-glycoside synthesis reported in the literature are limited. Among them, US20040048785A1 discloses a method for synthesizing C-glycoside derivatives from xylose and acetylacetone or dibenzoylmethane as raw materials by two-step reaction. The synthesis method of hydroxypropyl tetrahydropyran triol disclosed in CN202010643748.9 is similar to that of US20040048785A1, xylose and acetylacetone are used as raw materials, and the hydroxypropyl tetrahydropyran triol is obtained under the continuous action of alkali and sodium borohydride. CN201910785216.6 discloses a method for preparing hydroxypropyl tetrahydropyran triol (vitriol) by using xylose and ethyl acetoacetate as raw materials and a scandium complex as a catalyst and promoting hydrolysis decarboxylation and carbonyl reduction of ester groups. CN202010629023.4 discloses a method for preparing C-pyranoside, i.e. vitrein, by using a one-pot method of catalyzing the reaction of xylose and isopropanol with biological enzyme. In the process of synthesizing the C-glycoside derivative, acetylacetone, dibenzoylmethane, ethyl acetoacetate and isopropanol are all derived from fossil resources, and 100% biomass-based C-glycoside derivative is difficult to obtain. Therefore, it is important to develop a preparation method of biomass-based C-glycoside derivatives with high efficiency, convenience and high economy.
