Abstract

Strong support for the recently proposed structure of the kedarcidin chromophore has been obtained through the convergent synthesis of the aglycon. The key features of the synthesis are an efficient assembly of the four fragments, a novel strategy involving an alkynyl epoxide, a cerium amide promoted nine-membered diyne ring cyclization, and a SmI2-mediated reductive 1,2-elimination. TBS=tert-butyldimethylsilyl, MOM=methoxymethyl.
