intermediates provide a useful medium through which distant chiral centers may control chemical reactions. In this paper, we show that macrocycles made by cyclization of simple acyclic starting materials with an auxiliary spacer may be used to prepare stereochemically complex acyclic products.
大环中间体的构象提供了有用的介质,远处的手性中心可通过该介质控制化学反应。在本文中,我们表明,通过简单的无环起始材料与辅助间隔基环化制得的大环化合物可用于制备立体化学复杂的无环产物。
