摘要

Azafulvenium methides generated by the thermal extrusion of SO2 from 1-methyl-and 1, 1- dimethyl-1H, 3H-pyrrolo [1, 2-c] thiazole-2, 2-dioxides undergo [1, 8] H sigmatropic shifts to give vinylpyrroles. Flash vacuum pyrolysis of the C-vinylpyrroles affords 5-oxo-5H- pyrrolizines or C-allyl-1H-pyrroles.
