摘要

The application of a photochemical aromatic annulation strategy in highly efficient total syntheses of several diterpenoid quinones isolated from the traditional Chinese medicine Dan Shen is reported. The pivotal step in each synthesis involves the assembly of a key tricyclic intermediate via the application of a recently developed “second-generation” photochemical aromatic annulation method for the construction of highly substituted ...
