摘要：

Reactions between magnesium 1,4-dihydropyridide or 1,2-dihydroiso-quinolide derivatives and carbodiimides, RN=C=NR, generally result in Mg-N insertion and formation of guanidinate complexes. More sterically perturbed systems with N-aryl carbodiimide substitution, however, follow a divergent course of reaction initiating heterocyclic ring contraction and pyrrolide formation under unprecedentedly mild conditions.
