flavors contained in green teas, and its homologs have been synthesized by the reactions of several metallic salts of L-pyrrolidonecarboxylic acid with primary alkylamines. Hitherto, γ-alkylamides of L-glutamic acid had been prepared in low yields by the reactions of L-pyrrolidonecarboxylic acid with anhydrous alkylamines. The use of metallic salts, especially cupric, zinc, and manganese salts, increased
L-茶氨酸是绿茶中香料的主要成分,它的同系物是通过 L-吡咯烷酮羧酸的几种金属盐与伯烷基胺反应合成的。迄今为止,通过L-吡咯烷酮羧酸与无水烷基胺的反应以低收率制备了L-谷氨酸的γ-烷基酰胺。使用金属盐,尤其是铜盐、锌盐和锰盐,显着提高了γ-酰胺的产率。
