  Asymmetric Synthesis of the Fully Functional Macrolide Core of Salicylihalamide:  Remote Control of Olefin Geometry during RCM

  摘要：

  [GRAPHICS]A catalysis-based approach to the core region 24 of the antitumor agents salicylihalamides A and B is reported. Key steps are two asymmetric hydrogenations of beta -keto esters 13 and 16 catalyzed by [(R)-BINAP-RuCl2](2). NEt3 and an RCM-based macrocyclization effected by the NHC-containing ruthenium carbene 21. The stereochemical outcome of the tatter reaction is controlled by remote substituents on the phenolic OH group of the cyclization precursor 23.
