selective isomerization of various terminal N‐Boc protected aziridines to enamides was realized using the highly reactive nucleophilic rhodium catalyst C with the Lewisacid LiNTf2 as co‐catalyst under moderate conditions. The reaction proceeds smoothly with only 1 mol% catalyst loading and excellent yields were achieved. An intermediate containing an enamide with a non‐conjugated terminal C=C double bond
An efficient cobalt-catalyzed asymmetrichydrogenation of internal simple enamides has been developed, especially its convergent pattern for E/Z-substrates. Excellent enantioselectivity, wide substrate scope, and valuable applications were shown.
