摘要

Tetrahydroisoxazole-5-spirocyclopropanes 3, prepared by cycloaddition of nitrones 1 to methylenecyclopropane (2), have been converted by thermolysis into heterocyclic ketones 5 of the piperidine or indolizine or quinolizine series, according to the structure of the starting nitrone. The enaminones 6 are obtained as side products, as a result of 1, 5 H-transfer on the assumed intermediates 7. This procedure has been applied to the preparation of ...
