The first catalytic endo-selective 1,3-dipolar cycloaddition of azomethine ylides and vinyl phenyl sulfone has been developed successfully. The highly efficient silver acetate (AgOAc)/TF-Bi-phamPhos catalytic system exhibited high reactivity, excellent diastereoselectivity (> 98:2), good enantiosele

## 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
