A unified diastereo- and enantiocontrolled entry into compactin lactone, an essential structural moiety for the biological activity of compactin, and calcitriol enyne, an A-ring precursor of calcitriol, has been developed by use of the same stereocontrol procedure starting from enantiomeric epichlorohydrins.
通过使用相同的立体控制程序,从对映体环氧氯丙烷开始,开发出了一种统一的非对映和对映体控制的方法,可用于制备紧凑素内酯(紧凑素生物活性的重要结构分子)和降钙素三醇的 A 环前体降钙素三醇炔。

A facile chiral synthesis of (4R,6S)-4-hydroxy-6-hydroxymethyltetrahydro-2-pyrone (3) a key synthon for the lactone portion of compactin and mevinolin, is established using (R)-O-benzylglycidol as starting material.
