Unexpected O â S and N â S alkyl transfer reactions were observed in the reaction of 3-alkyl-2-(N-cyanoimino)thiazolidines with sodium alkoxides, and a new synthetic method for cimetidine was developed using the N â S alkyl transfer reaction as a key step.
在 3-烷基-2-(N-氰基亚胺)噻唑烷与烷氧基化钠的反应中,观察到了意想不到的 O - S 和 N - S 烷基转移反应,并以 N - S 烷基转移反应为关键步骤,开发出了一种新的西咪替丁合成方法。
