Studies toward the Synthesis of the Epoxykinamycin FL-120B′: Discovery of a Decarbonylative Photocyclization
摘要:
Photo-Friedel-Crafts a cylation of a naphthoquinone was attempted in an effort to access a diazobenzofluorenone en route to the epoxykinamycin natural product FL-120B'. Photoirradiation of the naphthoquinone substrate which resulted in the unexpected formation of a tetracyclic naphthofuran via a decarbonylative photocyclization process is described.

The enantioselective totalsynthesis of the diazobenzofluorene antibiotic (-)-kinamycin C is reported. The approach involves tartrate-mediated, asymmetric nucleophilic epoxidation of a functionalized quinone monoketal to construct the highly substituted D-ring.
