  功能化酮的 Baeyer-Villiger 氧化中区域选择性和对映选择性的催化剂控制

  摘要：

  我们报告了一种基于肽的催化剂，它可以强烈影响带有酰胺、尿素或磺酰胺官能团的环酮的 Baeyer-Villiger (BV) 氧化的区域和对映选择性。两种类型的选择性都被认为是由催​​化剂-底物氢键相互作用引起的。此外，在选定的情况下，反应表现出平行动力学分辨率的标志。在不对称过程中使用催化在 BV 产品之间进行选择的能力可能对复杂分子（包括天然产品）的合成和多样化具有广泛的用途。

  Divergent Stereoselectivity in Phosphothreonine (pThr)-Catalyzed Reductive Aminations of 3-Amidocyclohexanones

  摘要：

  Phosphothreonine (pThr)-embedded peptide catalysts are found to mediate the reductive amination of 3-amidocyclohexanones with divergent selectivity. The choice of peptide sequence can be used to alter the diastereoselectivity to favor either the cis-product or trans-product, which are obtained in up to 93:7 er. NMR studies and DFT calculations are reported and indicate that both pathways rely on secondary interactions between substrate and catalyst to achieve selectivity. Furthermore, catalysts appear to accomplish a parallel kinetic resolution of the substrates. The facility for phosphopeptides to tune reactivity and access multiple products in reductive aminations may translate to the diversification of complex substrates, such as natural products, at numerous reactive sites.

  日期：2007.12.1

  A series of carbamates, amides, N-tosyl amides, (hetero)arenes, and hydrogen phosphines/phosphites has been examined as nucleophiles for (hetero)Michael-type additions to enones and enamides catalyzed by amphoteric vanadyl triflate under mild and neutral conditions. The newly developed C-N, C-P, and C-C bond-formation protocols were carried out smoothly in good to high yields without intervention of any 1,2-additions.
