activation of tertiary amines provide one of the cornerstones of modern organic synthesis. Here we describe a palladium-catalyzed selective CN bond cleavage of N-propargyl 1,3-oxazolidines, providing an efficient approach to a diverse range of oxazolines in good to excellent yields. The reaction proceeds through a domino process of the alkyne-enabled 1,5-hydrogen transfer/CN bond activation. In this
能够选择性活化叔胺的 C N 键的策略是现代有机合成的基石之一。在这里,我们描述了钯催化的N-炔丙基 1,3-恶唑烷的选择性 CN 键断裂,为多种恶唑啉的产率良好到优异提供了一种有效的方法。该反应通过炔烃启用的 1,5-氢转移/C N 键激活的多米诺骨牌过程进行。通过这种方式,形成了两种耐受多种官能团的恶唑啉骨架。
