Studies of monoalkylation of the dianion generated from 2-(5-oxazolyl)-1,3-dithiane led exclusively to substitution adjacent to sulfur. However, acylation reactions of afforded 4,5-disubstituted oxazoles as novel examples of direct acylation of the oxazole nucleus.
由2-(5-
恶唑基)-1,3-二
噻吩生成的二价阴离子的单烷基化研究仅导致与
硫相邻的取代。然而,提供的4,5-二取代的
恶唑的酰化反应作为
恶唑核直接酰化的新实例。
