Abstract

The invention discloses a method for synthesizing cytidine diphosphate, and belongs to the field of nucleoside synthesis in organic chemistry. The method comprises the following reaction steps that cytidine monophosphate and dichlorophosphoryl morpholine serve as raw materials, condensation is conducted under the base catalysis effect, then a crude product cytidine diphosphate is obtained through acyl chloride hydrolysis, recrystallization is conducted through an alcohol / water mixed system, and a finished cytidine diphosphate product with the HPLC purity larger than 95% is obtained. The whole reaction only comprises two steps, reaction operation is simple, and the total yield reaches 70% or above.

Description

technical field [0001] The invention belongs to the field of organic chemistry and relates to the synthesis of pyrimidine dinucleotide, in particular to a method for synthesizing cytidine diphosphate. Background technique [0002] Cytidine diphosphate, chemical name: cytidine-5'-diphosphate, CAS number: 63-38-7, molecular formula is C 9 h 15 N 3 o 11 P 2 , an important raw material for the synthesis of polymyocytes. At present, the synthesis methods of cytidine diphosphate mainly include: [0003] The first type: biosynthetic method Hendrik Zipse et al. used Escherichia coli to use cytidine as a raw material for biotransformation into cytidine diphosphate. [0004] The second type: the chemical synthesis method uses cytidylic acid morpholine and morpholine tri-n-butylamine salt as raw materials, and undergoes condensation under the catalysis of DCC to obtain cytidine diphosphate. Céline Crauste and others catalyzed the synthesis of nucleoside diphosphates by soluble p...
