A synthesis of (S)-manoalide diol (2a) has been achieved using 2-deoxy-D-ribose as starting material to unequivocally supply the stereochemistry. Reduction of natural manoalide afforded enantiomeric manoalide diol 2b. Thus, the absolute configuration of manoalide is R (as depicted in 1).
使用2-脱氧-D-核糖作为起始材料明确地提供立体化学,已经实现了(S)-甘露糖醇二醇(2a)的合成。还原天然的山梨糖醇得到对映体的山梨糖醇二醇2b。因此,山梨醇内酯的绝对构型为R(如1所示)。
