本文描述了一种构建具有立体定义的单环和双环外亚烷基γ-内酰胺的汇聚过程,该过程通过β-卤代烯丙醇、芳香亚胺和一氧化碳的结合来进行。总体而言,区域选择性和立体选择性的钛介导的还原交叉偶联,接着是钯催化的羰基化反应,可以通过一锅法或两步法进行,为杂环合成定义了一种高度选择性的三组分偶联过程。
A convergent process for the assembly of stereodefined mono- and bicyclic exo-alkylidene γ-lactams is described that proceeds through the union of β-halo allylic alcohols, aromatic imines and CO. Overall, regio- and stereoselective Ti-mediated reductive cross-coupling, followed by Pd-catalyzed carbonylation can be performed in a one or two-pot procedure, defining a highly selective three-component coupling process for heterocycle synthesis.
