摘要：

Carbonyl‐activated diazo compounds and enamines (acyclic or with a six‐membered ring) undergo 1,3‐dipolar cycloaddition. The invariant orientation of the reactants is remarkable: the initial products are 4‐aminopyrazolines such as 1. In contrast, the (partly isolable) zwitterions 2 formed as primary products from enamines with a five‐membered ring arise by azo coupling. (Figure Presented.)
