A new tetrahydropyran scaffold has been efficiently prepared by Prins reaction between hepta-1,6-dien-4-ol and benzaldehyde. Subsequent functionalizations were further achieved by Mitsunobu reaction and/or by the way of cross-metathesis/Wacker oxidation sequence to deliver diospongin A analogues.
通过庚-1,6-二烯-4-醇和苯甲醛之间的 Prins 反应,有效地制备了一种新的四氢吡喃支架。随后,通过三忍反应和/或交叉甲基化/瓦克氧化顺序,进一步实现了官能化,从而得到了二蛇床子素 A 类似物。
