## 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

The 3-methylenecephams underwent I .3-dipolar cycloaddition reactions with diazomethane to give spiropyrazolinocephams in a completely stereo-and regioselective manner. Thermal breakdown of these I-pyrazolines led to spirocyclopropane and vinyl derivatives.

Lewis base catalysed 1,3-dipolar cycloaddition between α,β-unsaturated acyl fluorides and N-[(trimethylsilyl)methyl]amino ethers has been achieved using 1 mol% DMAP. Competition experiments and (19)F-NMR studies indicate that the cycloaddition occurs preferentially between the α,β-unsaturated acyl f
