  • Stereoselective synthesis of alicyclic ketones: A hydrogen borrowing approach
    作者:Roly J. Armstrong、Wasim M. Akhtar、James R. Frost、Kirsten E. Christensen、Neil G. Stevenson、Timothy J. Donohoe
    DOI:10.1016/j.tet.2019.130680
    日期:2019.11
    A highly diastereoselective annulation strategy for the synthesis of alicyclic ketones from diols and pentamethylacetophenone is described. This process is mediated by a commercially available iridium(III) catalyst, and provides efficient access to a wide range of cyclopentane and cyclohexane products with high levels of stereoselectivity. The origins of diastereoselectivity in the annulation reaction
    描述了一种由二醇和五甲基苯乙酮合成脂环族酮的高度非对映选择性环化策略。该方法由可商购的铱(III)催化剂介导,可有效地获得各种具有高立体选择性的环戊烷和环己烷产品。通过一系列控制实验探索了环空反应中非对映选择性的起源,这为如何控制新锻造环周围的每个立体中心提供了解释。
