• Catalytic Reductions and Tandem Reactions of Nitro Compounds Using in Situ Prepared Nickel Boride Catalyst in Nanocellulose Solution
  作者：Kaniraj Jeya Prathap、Qiong Wu、Richard T. Olsson、Peter Dinér

  DOI：10.1021/acs.orglett.7b02090

  日期：2017.9.15

  A mild and efficient method for the in situ reduction of a wide range of nitroarenes and aliphatic nitrocompounds to amines in excellent yields using nickel chloride/sodium borohydride in a solution of TEMPO-oxidized nanocellulose in water (0.01 wt %) is described. The nanocellulose has a stabilizing effect on the catalyst, which increases the turnover number and enables low loading of nickel catalyst

  描述了一种温和有效的方法，用于在TEMPO氧化的纳米纤维素水溶液（0.01 wt％）中使用氯化镍/硼氢化钠以优异的产率将多种硝基芳烃和脂肪族硝基化合物原位还原为胺。纳米纤维素对催化剂具有稳定作用，这增加了周转次数，并使镍催化剂（0.1–0.25 mol％NiCl 2）的负载量较低。另外，开发了两个串联方案，其中将原位形成的胺用Boc保护成氨基甲酸酯，或进一步与环氧化物反应，以优异的产率产生β-氨基醇。

  a series of pyrrolo[3, 2-d]pyrimidine derivatives was prepared and evaluated for their ability to bind to Y5 receptors in vitro. We report here the synthesis and initial structure-activity relationship investigations for this class of compounds. The target compounds were prepared by a variety of synthetic routes designed to modify both the substitution and the heterocyclic core of the pyrrolo[3,2-d]pyrimidine
