Abstract

The first method for the direct formation of α-oxycarbonates from both aldehydes and ketones is described. N-Methyl-O-alkoxyformate hydroxylamine hydrochloride reagents can be prepd. in two high-yielding steps from N-Boc-N-methylhydroxylamine and were found to be bench stable. These were reacted with a variety of carbonyl compds. to give the corresponding α-functionalized products in 48-98% isolated yield via a proposed [3,3]-sigmatropic rearrangement.
