synthesis of N‐alkyl‐N‐alkyloxycarbonylaminomethyl (NANAOCAM) prodrugs of acetaminophen, theophylline, and 6‐mercaptopurine by alkylation of the corresponding drug molecule with N‐alkyl‐N‐alkyloxycarbonylaminomethyl chlorides in good yield. Most of the alkylating agents were efficiently synthesized by chloromethylation of N‐alkyl carbamic acid alkyl esters, which in turn were made from alkyl amines and
摘要 我们报告了对乙酰氨基酚、茶碱和 6-巯基嘌呤的 N-烷基-N-烷氧基羰基氨基甲基 (NANAOCAM) 前药的新合成,通过用 N-烷基-N-烷氧基羰基氨基甲基氯化物对相应的药物分子进行烷基化,收率良好。大多数烷基化剂是通过 N-烷基氨基甲酸烷基酯的氯甲基化有效合成的,而 N-烷基氨基甲酸烷基酯又由烷基胺和氯甲酸烷基酯制成。在没有氯甲酸烷基酯的情况下,N-烷基氨基甲酸烷基酯的合成是通过将醇转化为氯甲酸酯或活化酰化剂如酰基咪唑或对硝基苯基碳酸酯,然后与烷基反应来完成的。胺类。
