## Abstract Azomethine ylides generated from 5β(alkoxycarbonylmethyl)phenanthridinium cations were studied in 1,3βdipolar cycloadditions with dimethyl maleate and dimethyl fumarate as dipolarophiles. The cycloadducts with the pyrrolidino[1,2βf]phenanthridine skeleton easily underwent dehydrogenatio
