  磷酸衍生物催化酸酐被酸酐酰化的机理研究

  摘要：

  洞察安全，简单且廉价的磷酸（H 3 PO 4描述了醇用酸酐的）催化的酰化。与传统上提出的单酰化混合酸酐不同，提出了相应的原位生成的二酰化混合酸酐作为活性物质。特别地，二酰基化的混合酸酐充当有效的催化酰基转移试剂，而不是充当简单活化酸酐的布朗斯台德酸催化剂。值得注意的是，实现了高效磷酸（1-3 mol％）催化的醇与酸酐的酰化作用，并证明了23 g规模的酯的合成。另外，磷酸催化剂对于从羧酸，醇和酸酐的合成有用的酯化是有效的。此外，关于手性1的最新发展，1'-联-2-萘酚（BINOL）衍生的磷酸二酯催化剂通过酰化作用对醇的不对称动力学拆分，研究了一些磷酸二酯。结果，31 P NMR研究和动力学研究不仅大力支持了其他研究人员先前提出的酸碱协同机理，而且也大力支持了我们目前提出的混合酸酐机理。
