Strategies to enantiopure 6-hydroxy-δ-valerolactones, through bis-epoxide formal equivalents issued from L-ascorbic and D-isoascorbic acids, are studied. The approaches notably involve Mitsunobu reaction on diols or triols and opening of the resulting epoxides.
研究了通过从L-
抗坏血酸和
D-异抗坏血酸发出的双
环氧化物形式等效物来制取对映纯6-羟基-
δ-戊内酯的策略。所述方法特别涉及在二醇或三醇上的Mitsunobu反应和打开所得的
环氧化物。
