Abstract:The preparation of 6-chloro-5-nitrothieno[3,2-e][1,3]thiazin-4-one incorporating 2-(N-morpholinyl) moiety, is achieved via a conventional route. Interaction of the latter substrate with a set of N'-(aryl) benzothiohydrazides 1a-f, in the presence of triethylamine, led to a thiophene ring-opening process with the consequent generation of the respective thiolate salts 8a-f. Alkylation of the
摘要:通过常规途径制备了含有2-(N-吗啉基)基团的6-氯-5-硝基噻吩并[3,2-e][1,3]噻嗪-4-酮。后一种底物与一组 N'-(芳基) 苯并硫酰肼 1a-f 在三乙胺存在下的相互作用导致噻吩开环过程,随后产生相应的硫醇盐 8a-f。后者使用甲基碘或烯丙基氯进行烷基化,生成各自的新型 1,3,4-噻二唑啉-6-硫烷基-1,3-噻嗪-4-one 杂化物,其结构通过 HRMS 和 NMR 光谱验证数据。
