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