Study on Synthesis of 5-(Substituted phenyl)-2H-pyran-2-one
ZHANG Hui1,WANG Yan2,CHEN Rong-rong1,LIU Yu-qian1,ZHAO Ai-hua1,XU Yong-nan1 (1. School of Pharmaceutical Engineering,Shenyang Pharmaceutical University,Shenyang 110016,China;2. Northeast Pharmaceutical Group Co.,Ltd.,Shenyang 110026,China)
Abstract:The title compound was synthesized from phenyl acetaldehyde via Michael addition,acidification,cyclization,bromination and dehydrogenation. The structure of the target compound was confirmed with 1H NMR and MS. Upon optimization of the reaction conditions were obtained:n(enamine)∶n(acrylic ester)=1∶1.5,n(NBS)∶n(5)=10∶1,and the cyclization reaction time 14 h. The process gave the product in overall yield of 32% under the optimum conditions.
Key words:2H-pyran-2-one;synthesis;anticancer
