FACILE SYNTHESIS OF 2,3-DISUBSTITUTED PYRROLES FROM 2-SUBSTITUTED 1-PYRROLINES

[摘要]：2-Substituted-1-pyrrolines react with various arylaldehyde acetals in the presence of a Lewis acid and base to give 2-substituted 3-arylmethylidene-1-pyrrolines, which are transformed to 2,3-disubstituted pyrroles by base-catalyzed double-bond isomerization.
