The first total synthesis of a sesquiterpenoid, tenuifolin, was achieved in seven linear steps. Phenyliodine(III) bis(trifluoacetate) (PIFA) mediated oxidative biaryl coupling was employed as a key step to construct the central seven-membered ring wi

Dehydrogenation by IBX/p-TsOH is applied to the conversion of 3-benzoyl propionates/propionamides to 3-benzoyl acrylates/acrylamides in moderate to excellent yields. The reaction time for the dehydrogenation of 3-benzoyl propionamides was remarkably
