Efficient asymmetric syntheses of both naturally occurring and non-naturally occurring enantiomers of gonioheptolide A are reported. The absolute configuration of (+)-gonioheptolide A was established by NOESY, Mosher ester analysis, and comparison with the specific rotation of the isolated (+)-gonioheptolide A.
报道了天然和非天然的戈尼庚醇A对映异构体的高效不对称合成。通过NOESY、Mosher酯分析以及与分离得到的(+)-戈尼庚醇A的特定旋光度进行比较,确立了(+)-戈尼庚醇A的绝对构型。
