1-[2-(4-Hydroxybenzoyl)ethanoyl]-2-piperidone and a process for production as well as alcohol fermentation promoter containing the same as effective ingredient
 The present invention relates to 1-[2-(4-hydroxybenzoyl)ethanoyl]-2-piperidone which is a novel compound of N-acyl lactam compounds and exhibit excellent effects in promoting fermentation in alcohol fermentation. This novel compound can be prepared by converting 2-(4-benzyloxybenzoyl)acetic acid into the acid chloride, then coupling the acid chloride with 2-piperidone or an alkylate of 2-piperidone and then subjecting to debenzylation.
