A Novel Reactivity of α-Nitro Ketone Tosylhydrazones with DBU. Synthesis of α,β-Unsaturated Enone Tosylhydrazones.

Ballini, Roberto,Giantomassi, Gianni

, p. 4173 - 4182 (2007/10/02)

Treatment of α-nitro ketone tosylhydrazones with DBU gives 1,4-elimination of nitrous acid affording 1-tosylazoalkenes which, under basic conditions (DBU), tautomerize to the more stable enone tosylhydrazones.The obtained tosylhydrazones may be used as st
