• N1-Selective Methylation of Pyrazoles via α-Halomethylsilanes as Masked Methylating Reagents
  作者：Emma Yang、Derek M. Dalton

  DOI：10.1021/acs.joc.3c02841

  日期：2024.3.15

  The development of a highly selective N-methylation of pyrazole heterocycles using commercially available, bench-stable α-halomethylsilanes as masked methylating reagents is described. Sterically bulky α-halomethylsilanes significantly improve the selectivity of N-alkylation over traditional methylating reagents and readily undergo protodesilylation in the presence of a fluoride source and water to

  描述了使用市售的、实验室稳定的 α-卤甲基硅烷作为掩蔽甲基化试剂开发吡唑杂环的高选择性 N-甲基化。与传统的甲基化试剂相比，空间庞大的 α-卤甲基硅烷显着提高了 N-烷基化的选择性，并且在氟化物源和水存在下很容易进行原脱甲硅烷基化，得到N-甲基吡唑。使用一系列吡唑底物以良好的产率实现了 92:8 至 >99:1 N1/N2 区域异构比的选择性。
