The selective isomerization of various terminal N-Boc protected aziridines to enamides was realized using the highly reactive nucleophilic rhodium catalyst C with the Lewis acid LiNTf2 as co-catalyst under moderate conditions. The reaction proceeds smoothly with only 1 molpercent catalyst loading and excellent yields were achieved. An intermediate containing an enamide with a non-conjugated terminal C=C double bond was detected during the course of the reaction, which isomerizes to form the thermodynamically favored 2-amido styrene. Mechanistic insight is gained based on these observations.
