Title: alpha '-Hydroxy-alpha,beta-unsaturated tosylhydrazones: Preparation and use as intermediates for carbonyl and enone transpositions
Author: Baptistella, LHB
Alexio, AM
Abstract: Regiospecifically generated alpha,beta-unsaturated tosylhydrazones dianions are treated with molecular oxygen, yielding alpha'-hydroxy-alpha,beta-unsaturated tosylhydrazones, versatile intermediates for organic synthesis. They proved to be useful for 1,2-carbonyl and 1,2-enone transpositions, and also permitted the preparation of alpha'-hydroxy enones in very high yields.
