✦ Synopsis


Di-n-butyl telluride, 2-bromoacetylisobutylamide (or 2-bromoacetylpiperidide) react directly with saturated or +unsaturated aldehydes at room temperature in the presence of potassium carbonate(s) to afford (2E)-, or (2E, 4E)-unsaturated carboxylic acid amides, respectively, in excellent yields with high E stereoselectivity .
