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.
A photochemical aromatic annulation strategy provides efficient synthetic routes to the diterpenoid quinones (+)-danshexinkun A, danshexinkun B, danshexinkun C, (-)-dihydrotanshinone I, and tanshinone I.
