  Efficient and highly stereoselective syntheses of enantiomerically enriched C(1)-C(7) subunits of erythronolides

  摘要：

  Stereocontrolled efficient syntheses of the C(1)-C(7) fragments of deoxyerythronolide and erythronolide seco acids are described. The key step of these syntheses involves a highly stereoselective aldol condensation between an enantiomerically enriched 2-arylpropanal and the lithium enolate of the racemic 2-methyl-5-norbornenyl ethyl ketone, which establishes in one operation the relative and absolute configurations of the three stereocenters C(2), C(3), and C(4). After syn-selective reductions of the carbonyl group, the configuration required at carbon C(6) was introduced by highly selective reactions carried out on the double bond regenerated by a thermal cycloreversion.
