ADDITIONS REGIOSELECTIVES D'IMINES ET D'HYDRAZONES METALLEES AUX α-ENONES

Article abstract of DOI:10.1016/0040-4020(80)88005-7

The behavior of metallated imines and hydrazones toward α,β-unsaturated ketones was studied, using different reaction times and temperatures.Dissociation of the functional group (imine or hydrazone) in the adducts and regioselectivity in their condensation reactions are discussed.The first example of reversible addition to the carbonyl group of an enone is demonstrated for the reaction between trans chalcone and (1-)*Li(1+).
