  Stereoselective Synthesis and Determination of the Cytotoxic Properties of Spicigerolide and Three of Its Stereoisomers

  摘要：

  Stereoselective syntheses of the naturally occurring, cytotoxic lactone spicigerolide and three nonnatural stereoisomers thereof are described. The commercially available sugar L-rhamnose was in all cases the chiral starting material. Key steps in each of these syntheses were asymmetric Brown allylations and ring-closing metatheses. The cytotoxic activities of the four lactones against a range of tumoral lines were then determined.

  The first total synthesis of the naturally occurring, cytotoxic lactone spicigerolide is described. The commercially available sugar L-rhamnose was the chiral starting materal. Key steps in the synthesis were an aldehyde two-carbon homologation via the Corey-Fuchs protocol, an asymmetric Brown-type aldehyde allylation and a ring-closing metathesis.
