Diastereoselective Intramolecular Friedel–Crafts Cyclizations of Substituted Methyl 2-(1H-indole-1-carbonyl)acrylates: Efficient Access to Functionalized 1H-Pyrrolo[1,2-a]indoles
摘要:
A general, catalytic method for the diastereoselective synthesis of functionalized 1H-pyrrolo[1,2-a]indoles via an intramolecular Friedel-Crafts alkylation of N-acyl indoles Is reported. Products were obtained In excellent yields (up to 98%) with high diastereoselectivities (up to >25:1 dr).
