Pretazettine (1), which shows antileukemic activity, was obtained by conversion of tazettine (2) to 3-epitazettadiol (3) [whose structure was confirmed by its cyclization to deoxypretazettine (4)], followed by manganese dioxide oxidation of 3. The transformation of 2 to 1 confirmed the stereochemistry of pretazettine (1).
抗白血病活性的Pretazettine (1) 是通过将tazettine (2) 转化为3-epitazettadiol (3) 获得的 [其结构通过环化形成deoxypretazettine (4) 进行确认],随后对3进行二氧化锰氧化。这一转化确认了pretazettine (1) 的立体化学。
