An efficient ring-opening of aziridines with various carboxylic acids catalyzed by an organocatalyst-DBU afforded the corresponding products in good to excellent yield under mild reaction conditions.
Tin-Free Radical Addition of Acyloxymethyl to Imines
Acyloxymethyl radicals were generated from the corresponding iodomethyl esters and successfully underwent addition to the CN bond of N-Ts, N-PMP, and N-Dpp imines by the action of dimethylzinc or triethylborane. Ethyl acetate, toluene, and benzene as well as dichloromethane were suitable solvents. The utility of acyloxymethyl radicals as a hydroxymethyl anion equivalent was highlighted by the facile
