A simple and versatile one-pot procedure for the in situ generation of nitrilimines from N-acyl hydrazines is described. 1,3-Dipolar cycloadditions and 1,5-electrocyclic ring closures are carried out. Unsymmetrically substituted dipolarophiles show typical regioselectivity.
本文介绍了一种简单而通用的单锅程序,用于从 N-酰肼原位生成氮亚胺。该过程包括 1,3-二极环化反应和 1,5-电环闭环反应。 不对称取代的双极性化合物显示出典型的区域选择性。
