Abstract

A general method for converting aryl or alkyl methyl ketones to vinylhydrazinedicarboxylates via the Mitsunobu reaction is reported. Unsymmetrical alkyl ketones show high regioselectivity.

Key words

tributylphosphine - triphenylphosphine - dimethyl azodicarboxylate - vinylhydrazinedicarboxylates - Mitsunobu reaction
