Gold-Catalyzed Synthesis of 2-Aryl-3-fluoropyrroles
摘要:
The gold-catalyzed cyclization and dehydrofluorination of gem-difluorohomopropargylamines provides a novel access to 2-aryl-3-fluoropyrroles. Difluorinated homopropargylamines are prepared by the addition of gem-difluoropropargyllithium reagents to arylated N-tosylimines.
