Caught in the middle: The ionomycin calcium complex (see structure; O red, Ca green) was the target of an approach featuring the efficient asymmetric synthesis of an allene by a copper(I)‐mediated anti‐selective SN2′ reaction, a highly stereoselective gold(III)‐catalyzed cycloisomerization of an α‐hydroxyallene, and a Rh‐catalyzed rearrangement of an α‐diazo‐β‐hydroxyketone.
陷入中间:离子霉素钙络合物(见结构; O红,Ca绿)是通过铜(I)介导的抗选择性S N 2'反应有效地不对称合成丙二烯的方法的目标,高度立体选择性的金(III)催化α-羟基丙烯的环异构化,以及Rh-催化的α-重氮β-羟基酮的重排。
