Title: α′-hydroxy-α,β-unsaturated Tosylhydrazones: Preparation And Use As Intermediates For Carbonyl And Enone Transpositions
Author: Baptistella L.H.B.
Aleixo A.M.
Abstract: Regiospecifically generated α,β-unsaturated tosylhydrazones dianions are treated with molecular oxygen, yielding α′-hydroxy-α,β-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 α′-hydroxy enones in very high yields.
