protected as a 2,3-dimethoxybutanediyldioxy ketal, provides an excellent template for further highly stereoselective elaboration as exemplified by its conversion into the core of scyphostatin, a potent inhibitor of neutral sphingomyelinase.
[反应:参见正文]由(-)-奎宁酸衍生的烯酮,其反式1,2-二醇被保护为2,3-二甲氧基丁烷二基二氧基缩酮,为进一步高度立体选择性的修饰提供了极好的模板,如其转化所举例说明的进入鞘磷脂抑制素的核心位置,鞘磷脂抑制素是一种有效的中性鞘磷脂酶抑制剂。
