tertiary alcohols represents a recurrent challenge in organic synthesis. In the present paper, we describe a simple, efficient, and indirect method to enantioselectively prepare tertiary alcohols through a chiral isothiourea catalyzed selective acylation of adjacent secondary alcohols. This transformation enables the kinetic resolution (KR) of easily prepared racemic diastereoenriched secondary/tertiary
叔醇的立体控制代表了有机合成中反复出现的挑战。在本文中,我们描述了一种通过手性异硫脲催化相邻仲醇的选择性酰化来对映选择性制备叔醇的简单、有效和间接的方法。这种转化使易于制备的外消旋非对映体富集的仲/叔二醇的动力学拆分 (KR) 能够以高度对映体富集的形式提供单酯和起始二醇 ( s值 >200)。
