Base-promoted reactions of benzotriazolyl-containing acetic acid derivatives, 2- (benzotriazol-1-yl) acetonitrile (7a), 2-(benzotriazol-1-yl) acetamide (7b), and (±)-2- (benzotriazol-1-yl) propionamide (7c), with α, β-unsaturated ketones 8 give efficient and regioselective access to previously difficult to attain 3-unsubstituted pyridine derivatives: the 2-(substituted amino) pyridines 14a-k and the 4, 6-substituted pyrid-2-ones 15a-h. The ...
