the synthesis of N-acyl-N,O-hemiacetals has been reported. The key feature of this protocol is that it allows for direct access to electrophilic N-acylimines at room temperature without prefunctionalization of the hydroxyl group. The in situ generated N-acylimine can react with different nucleophiles, viz., alcohols, thiols, and nitriles, to afford a diverse range of scaffolds such as N,O-, N,S-, and
已经报道了一种温和的电子供体-受体复合物介导的合成N-酰基-N,O-半缩醛的方法。该方案的主要特点是它允许在室温下直接接触亲电子的N-酰亚胺,而无需对羟基进行预官能化。原位生成的N-酰亚胺可以与不同的亲核试剂(即醇、硫醇和腈)反应,提供多种支架,例如N,O-、N,S-和N,N-缩醛。
