Abstract

2-Aminouracil is used in the synthesis of a new series of tri- and tetracyclic pyrimidine scaffolds as the precursor. Thiazolo[5,4-d]triazolo[4,3-a]pyrimidine has been synthesized by diazotization and heterocyclization of the aminopyrimidinone derivative with nitrous acid at low temperature. Some new pyrimidines have been formed in the course of acylation and cyclization of the same compound with acetic anhydride, formic acid, pyruvic acid, or phthalic anhydride.

2-氨基-3-苄基-6-（苄硫基）嘧啶-4（3 H）-one的功能：多环嘧啶骨架合成的有效途径。

摘要

2-氨基尿嘧啶用于合成一系列新的三环和四环嘧啶骨架作为前体。噻唑并[5，4- d ]三唑并[4，3- a ]嘧啶是通过在低温下将亚氨基嘧啶酮衍生物与亚硝酸重氮化和杂环化而合成的。在相同化合物与乙酸酐，甲酸，丙酮酸或邻苯二甲酸酐的酰化和环化过程中，已经形成了一些新的嘧啶。
