摘要：

This protocol describes the synthesis of 6,7-methylenedioxy-4-phenylcoumarin from sesamol and ethyl phenylpropiolate using a Pd(OAc)(2) catalyst to illustrate coumarin synthesis. This procedure is simple and easy and can be applied to the synthesis of other coumarins that have electron-rich phenol groups. The reaction is conducted by stirring a solution of Pd( OAc)(2), sesamol and ethyl phenylpropiolate in trifluoroacetic acid at room temperature (15-20 degrees C) under atmospheric conditions. This protocol can be completed in 3 d.
