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.
