  Direct Imine Acylation: Rapid Access to Diverse Heterocyclic Scaffolds

  摘要：

  A simple and efficient procedure to prepare a range of diverse heterocycles by the direct acylation of imines using a variety of functionalized benzoic acids is described. The methodology features a novel method for N-acyliminium ion generation followed by in situ intramolecular trapping by oxygen-, nitrogen-, sulfur- and carbon-based nucleophiles. Preliminary mechanistic studies, using ReactIR, are also reported.

  The direct imine acylation (DIA) and subsequent cyclisation of a range of imines with ortho-substituted benzoic acid derivatives is described. Variation in the coupling reagents, imine and benzoic acid were all examined. The DIA procedure was also applied in the total synthesis of (±)-cavidine.
