  General and Asymmetric Synthesis of Protected 1,3,5-Triols with Pendant Functional Groups

  摘要：

  A stereoselective synthesis of enantiomerically purl 1,3,5-triols of any configuration has been developed. These triols carry suitable functional groups at the termini of the chain which should allow for easy and efficient coupling of two building blocks. The silyloxy-Cope rearrangement of syn-aldols was used to prepare a common advanced intermediate for the synthesis of all four stereoisomeric triols. Three synthetic operations-an allylboration, an oxidative desilylation, and a conjugate addition reaction-were employed to assemble the target molecules. Their terminal double bond may either be cleaved to give the corresponding aldehydes or oxidized to the methyl ketones in a Wacker process to provide access to two subunits for a coupling reaction.
