摘要

NEW MATERIAL:An N-acyllactam compound shown by formula I (n is 0-3). EXAMPLE:2-Benzoylformyl-2-piperidone. USE:An alcoholic fermentation promoter. The ratio of the promoter used is generally 0.00001-0.001W/V% based on fermented solution. PREPARATION:A compound shown by formula II is treated with oxalyl chloride, etc., and coupled with 2-piperidone or an alkylated 2-piperidone at room temperature or a temperature lower than the room temperature to give a compound shown by formula I.
