以不同取代的苯为原料, 经Friedel-Crafts酰基化、酯化、Mannich反应得到3-亚甲基-4-取代苯基-4-氧代丁酸甲酯(1a1g), 再与2-氨基苯硫酚进行Michael加成和分子内环和, 合成了一系列4-取代苯基-2,3-二氢-1,5-苯并硫氮杂卓- 3-乙酸甲酯并水解了其中的4个化合物, 产物的结构经IR, 1H NMR, MS和元素分析确证.

关键词: 1,5-苯并硫氮杂, Mannich反应, 合成

Starting from substituted benzenes, methyl 3-methylene-4-substituted phenyl-4-oxo-butanate (1a1g) were synthesized by Friedel-Crafts acetylation, esterification and Mannich reaction, then reacted with 2-amino benzenethiol getting a series of methyl 4-substituted-phenyl-2,3-dihydro-1,5-benzothiazepine- 3-acetates and their sodium salts. The structures of the new products were confirmed by 1H NMR, IR, MS techniques and elemental analysis.

Key words: 1,5-benzothiazepines, Mannich reaction, synthesis
