The reaction of N-tert-butylnitrones (1a-e) of aldehydes and N-methylnitrones (2 and 3) of cyclic ketones with acid chlorides in the presence of triethylamine afforded α-acyloxy imines by rearrangement of N-vinyl-O-acylhydroxylamine intermediates.Hydrolysis of the α-acyloxy imines gave α-acyloxy aldehydes and ketones.The acylation-rearrangement reaction offers a new method for α-oxygenation of carbonyl compounds.
