Ultrasound-Promoted synthesis of substituted phenanthrene-1,4-quinones; the structure of plectranthon D
摘要:
A series of tanshinone-type diterpenoids was prepared by ultrasound-promoted and Lewis acid catalyzed, highly regioselective cycloadditions of styrenes with substituted 1,4-benzoquinones as the key step.
