Syntheses of tetrahydropyrans ent-2 and ent-3, substructures of the A and B rings of the enantiomer of lasonolide A (1), are described. The syntheses of ent-2 and ent-3 feature highly stereoselective cycloetherification reactions of bis-homoallylic alcohols 7 and 8.
本文介绍了四氢吡喃 ent-2 和 ent-3 的合成,它们是拉索诺内酯 A(1)对映体 A 环和 B 环的亚结构。ent-2和ent-3的合成过程以双高脂醇7和8的高度立体选择性环醚化反应为特征。
