Tetrahydrofurfuroxy folic acid analogue synthetic method
-
Paragraph 0057; 0058; 0059, (2016/10/10)
The invention relates to a novel method for synthesis of tetrahydrofolic acid analogues, and mainly solves the problems of uneasily controllable reaction conditions and many produced by products in a conventional synthesis method. A series of tetrahydrofolic acid analogues are prepared by employing 5-aminouracil or 2,4,5,6-tetraaminopyrimidine, 2,5,6-triamino-4-hydroxypyrimidine as an initial raw material and combining the steps of cyclization, oxidation, chlorination, ammonolysis, catalytic hydrogenation reduction, intramolecular cyclization, aziridine ring opening, nucleophilic substitution, ethoxycarbonyl hydrolysis, etc. Compared with a conventional synthesis method, the novel method provided by the invention has the characteristics of mild and stable reaction conditions, few by-products, wide application range, etc.
