We have developed a concise, convergent, and stereocontrolled synthesis of (+/-)-leucascandrolide A (18 steps from commercially available precursors), featuring a complete relay of the initial stereochemical information via a series of diastereoselective transformations. Spontaneous macrolactolization discovered during this synthetic exercise has provided unprecedented access to this macrolide and
我们开发了 (+/-)-leucascandrolide A 的简洁、收敛和立体控制合成(从市售前体开始的 18 个步骤),具有通过一系列非对映选择性转化完整传递初始立体化学信息的特点。在这次合成练习中发现的自发大环内酯化提供了对这种大环内酯的前所未有的访问,并证明了以高度可控和有效的方式访问大环系统的可能性。
