The sequence of acylation of nitroalkanes and subsequent denitration of the resulting α-nitro ketones provides a new and general method for the preparation of ketones.
α-Methylene carbonyl compounds are regioselectively prepared by the reaction of α-nitroketones or α-nitroesters with 37% formaldehyde in the presence of a catalytic amount of weak bases followed by acetylation, denitration with Bu3SnH, and elimination of acetic acid.
