  Synthesis of optically active polyheterocycles containing pyrrolidine, imidazole, and 1,2,3-triazole rings

  摘要：

  Optically active polyheterocycles containing pyrrolidine, imidazole, and 1,2,3-triazole units were obtained via a multistep synthesis with the [3+2] cycloaddition of Boc-protected (S)-(pyrrolidin-2-yl) methyl azide with 2-ethynylimidazoles in the presence of CuI (CuAAC reaction) as the key step. Typical for terminal alkynes, the reactions occurred regioselectively and 1,4-disubstituted 1,2,3-triazoles were formed exclusively. The deprotection of the pyrrolidine N-atom was performed by treatment with TFA under standard conditions. (c) 2015 Elsevier Ltd. All rights reserved.

• Development of a Regioselective N-Methylation of (Benz)imidazoles Providing the More Sterically Hindered Isomer
  作者：Emilie Van Den Berge、Raphaël Robiette

  DOI：10.1021/jo401978b

  日期：2013.12.6

  An efficient and highly regioselective N-methylation of (NH)-(benz)imidazoles furnishing the sterically more hindered, less stable, and usually minor regioisomer has been developed. The methodology involves very mild reaction conditions and tolerates a wide range of functional groups.

  已经开发了一种高效且高度区域选择性的（NH）-（苯并）咪唑的N-甲基化，其提供在空间上更受阻，不太稳定并且通常为较小的区域异构体。该方法涉及非常温和的反应条件，并能耐受各种官能团。
