A new synthesis of theaspirone (10) is recorded. The key step involves coupling between the organolithium reagent 6, derived from 4-bromo-2-butanol (4), and the monoketal of 4-ketoisophorone (3). Removal of protecting groups and ether cyclization then gave theaspirone 10 and its diastereoisomer 11.
记录了theaspirone(10)的新合成。关键步骤涉及衍生自4-溴-2-丁醇(4)的有机锂试剂6与4-酮异佛尔酮(3)的单缩酮之间的偶联。除去保护基和醚环化,然后得到theaspirone 10和其非对映异构体11。
