  In our study of the total synthesis of (+)-irciniastatin A, we found a need to develop a method that enables a C3-selective nucleophilic ring opening of 2,3-epoxy alcohol by MeOH, by which we found that the use of combined catalytic amounts of Eu(OTf)3 and 2,6-di-tert-butyl-4-methylpyridine (DTBMP) enables the intended transformation to obtain 3-methoxy-1,2-diol efficiently. Promising features of a

  在我们对（+）-irciniastatin A的总合成的研究中，我们发现有必要开发一种方法，该方法能够使MeOH对2,3-环氧醇进行C3选择性亲核开环，从而发现使用Eu（OTf）3和2,6-二叔丁基-4-甲基吡啶（DTBMP）的组合催化量能够实现预期的转化，从而有效地获得3-甲氧基-1,2-二醇。描述了使用包括醇，硫醇和未保护的胺在内的各种亲核试剂实现2,3-和3,4-环氧醇的高度区域选择性亲核开环的方案的有前景的特征。

  We performed an organocatalyzed enantioselective kinetic resolution (KR) of racemic diastereocontrolled secondary alcohols bearing a quaternary stereocenter. This methodology is a general KR leading to the enantiocontrol of acyclic quaternary stereocenter with high levels of stereoselectivity (s up to 185) on a large scope. In addition, the hydroxyl function can easily serve as a traceless group by
