资源简介：
A Ag-catalyzed phosphorus radical promoted cyclization of cinnamamides to give exclusively 2-phosphinoyl-3H-pyrrolo[1,2-a]indoles derivatives via a 5-endo-trig manner is described. This novel reaction leads to the simultaneous formation of C–C and C–P bonds in one step with excellent chemo- (only 5-endo) and diastereoselectivity (dr >20:1) under mild conditions in moderate to good yields.
