2-Methylamino-2-thiazoline reacted with alkyl acyl halides to produce N-acyl-2-methylamino-2-thiazolines, exo-acylated product regioselectively, which were found to be highly chemoselective acylating agents for primary amine in the presence of secondary amine and for the less sterically hindered of two different primary amines.
2-甲基氨基-2-噻唑啉与烷基酰卤反应以产生Ñ酰基-2-甲基氨基-2-噻唑啉,外切-acylated产品区域选择性,这被认为是在仲胺的存在下伯胺高度化学选择性的酰化剂以及两种不同的伯胺在空间上受阻较小。
