The thermal migration of cyclic and acyclic organoboranes were studied. In most cases, a stereoselective 1,2-dyotropic migration was observed, allowing the stereocontrol of three contiguous chiral centers. Scope and limitations of this thermal migration are presented.
研究了环状和非环状有机硼烷的热迁移。在大多数情况下,可以观察到立体选择性的1,2-二向同性迁移,从而可以立体控制三个连续的手性中心。介绍了这种热迁移的范围和局限性。
