Abstract

I. VINYL BT's AS MICHAEL ACCEPTORS. An extensive and useful series of annulation processes could be developed if a reliable method were found for the conjugate addition of carbon nucleophiles to a, B-unsaturated aldehydes. However, direct 1, 4-addition to conjugated aldehydes is usually thwarted by addition at the carbonyl carbon. 2* 3 We now report that organo-lithium reagents undergo clean conjugate addition to the model vinyl ...
