A new synthesis of enamides from ketones involves a phosphine-mediated reductive acylation of oximes. The resulting enamides are isolated in good yields and excellent purity.

Among the reported examples of new reactivity of the hypervalent iodine reagent DMP (Dess-Martin periodinane) are the one-step oxidation of secondary amides to imides and N-acyl vinylogous carbamates or ureas and the direct oxidation of benzylic and related primary amines to the corresponding nitriles.

α,β-Dehydroamino acid derivatives were synthesized in good yields from α-bromoketones or α-bromoesters and hydroxamates via a sequential procedure involving displacement of bromide by hydroxamate anion, followed by a base-induced elimination-isomerization reaction.
