Base-mediated reaction of hydrazones and nitroolefins with a reversed regioselectivity: A novel synthesis of 1,3,4-Trisubstituted pyrazoles

A regioselective synthesis of 1,3,4-tri- or 1,3,4,5-tetrasubstituted pyrazoles by the reaction of hydrazones with nitroolefins is described. Mediated with strong bases such as t-Bu OK, the reaction exhibits a reversed, exclusive 1,3,4-regioselectivity. Su
