Formal radical cyclization onto benzene rings: a general method and its use in the synthesis of ent-nocardione A.
An indirect method is described for effecting radical cyclization onto a benzene ring. Cross-conjugated dienones 6, which are readily prepared from phenols, undergo radical cyclization (6 --> 7 --> 8), and the products (8) are easily aromatized. The method has been applied to the synth...
