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. |
