  使用1°和2°醇进行氢借入催化：导致α和β支链产物的研究和范围

  摘要：

  描述了在氢借位催化下使用1°或2°醇对各种酮进行的烷基化。最初的研究集中在环丙酮与更高的1°醇（即大于MeOH）的α-烷基化反应上，导致形成α-支化产物。我们通过寻找其他底物来探索这种化学反应，使我们发现，二邻位取代的芳基酮也是特有的支架，其中Ph ∗（C 6 Me 5）酮是最佳选择。进一步的研究表明，该基序对于与2°醇形成β支链产物的烷基化至关重要，这也为研究非对映选择性和分子内氢借入过程提供了机会。

  We describe the use of phenyl trimethylammonium iodide (PhMe3NI) as an alternative methylating agent for introducing a CH3 group in α-position to a carbonyl group. Compared to conventional methylating agents, quaternary ammonium salts have the advantages of being nonvolatile, noncancerogenic, and easy-to-handle solids. This regioselective method is characterized by ease of operational setup, use of

  variety of ketones using 1° or 2° alcohols under hydrogen borrowing catalysis is described. Initial research focused on the α-alkylation of cyclopropyl ketones with higher 1° alcohols (i.e. larger than MeOH), leading to the formation of α-branched products. Our search for additional substrates with which to explore this chemistry led us to discover that di-ortho-substituted aryl ketones were also privileged
