Catalytic divergent synthesis of 3H or 1H pyrroles by [3 + 2] cyclization of allenoates with activated isocyanides.

Jia-Yu Liao1, Pan-Lin Shao, Yu Zhao.   

Abstract

The cyclization of allenoates with activated isocyanides was reported for the first time. While Ag catalysis led to an unprecedented enantioselective synthesis of 3H pyrroles, a simple procedure using PPh3 produced a wide range of polysubstituted 1H pyrroles with high efficiency.
