  Secondary metabolites by chemical screening -13. Enantioselective synthesis of δ-lactones from streptenola, achiral building block from streptomyces

  摘要：

  The enantioselective synthesis of all four stereoisomers of the secondary metabolite 3-hydroxy-5-decanolide (4a) from Cephalosporium recifei and both enantiomers of massoialactone (5a) by starting from one chiral building block, streptenol A (1a), a secondary metabolite from Streptomyces sp., is described. The key steps of the reaction sequence involve diastereoselective reduction of 1a to syn- or anti-triol 2a and 2b and the regioselective oxidation of the primary hydroxyl group. This reaction furnishes in one step the sigma-lactones 3a and 3b and requires no protecting group.
