Bench stable N-Methyl-O-alkoxyformate hydroxylamine hydrochloride reagents can be prepared in two high-yielding steps from N-Boc-N-methyl hydroxylşamine. Subsequent reaction with various carbonyl compounds give the corresponding α-functionalised products in good yield via a proposed [3,3]-sigmatropic rearrangement.
