N-methylcarboximidoyl chloride affords after hydrolytic workup α-amidoketones. The results are interpreted in terms of the formation of an intermediate capable of undergoing a facile [3,3] sigmatropic rearrangement. Aldehyde derived nitrones form imides via a [3+2] cycloaddition reaction.
水解后的α-酰胺酮使酮衍生的硝酮与N-甲基羧酰亚胺基氯缩合。结果的解释是根据中间体的形成,该中间体能够进行容易的[3,3]σ重排。醛衍生的硝酮通过[3 + 2]环加成反应形成酰亚胺。
