The total synthesis of 12(R)-HETE, 12(S)-HETE (Samuelsson's HETE), [14,15-2H2]-12(R)-HETE and Leukotriene B4 from racemic glycidol is described. The key steps are the hydrolytic kinetic resolution of racemic TES-glycidol with salen-Co catalyst and the selective oxidation of primary silyl ethers, in the presence of secondary ones, under Swern conditions to give a short entry to both enantiomers of 12-HETE
12(的总合成- [R)-HETE,12(小号(Samuelsson所HETE))-HETE,[14,15- 2 H ^ 2 ] -12([R)-HETE和白三烯乙4从外消旋缩水甘油进行说明。关键步骤是在Swern条件下,在仲胺存在下,在Salen-Co催化剂的作用下,用Salen-Co催化剂水解外消旋TES-缩水甘油的动力学动力学和伯甲硅烷基醚的选择性氧化,以使12-HETE和对映体的两种对映异构体都短时间进入LTB 4。
