  Discovery and Structure–Activity Relationships of Pyrrolone Antimalarials

  摘要：

  In the pursuit of new antimalarial leads, a phenotypic screening of various commercially sourced compound libraries was undertaken by the World Health Organisation Programme for Research and Training in Tropical Diseases (WHO-TDR). We report here the detailed characterization of one of the hits from this process, TDR32750 (8a), which showed potent activity against Plasmodium falciparum K1 (EC50 similar to 9 nM), good selectivity (>2000-fold) compared to a mammalian cell line (L6), and significant activity against a rodent model of malaria when administered intraperitoneally. Structure-activity relationship studies have indicated ways in which the molecule could be optimized. This compound represents an exciting start point for a drug discovery program for the development of a novel antimalarial.

  Herein, the first example of base‐metal‐catalyzed dehydrogenative coupling of diols and amines to selectively form functionalized 1,2,5‐substituted pyrroles liberating water and hydrogen gas as the sole by‐products is presented. The reaction is catalyzed by pincer complexes of earth‐abundant cobalt.

  synthesis. Many nucleophilic reaction promoters, previously believed to be the catalysts, in fact primarily facilitated the formation of borane (BH3), which subsequently acted as the true catalyst. This revelation prompted us to explore the untapped potential of these unexpected transformations, with a view to simplify hydroboration using more cost-effective and environmentally friendly nucleophilic precatalysts

  隐藏硼烷催化的最新发现彻底改变了有机合成中催化硼氢化领域。许多亲核反应促进剂，以前被认为是催化剂，实际上主要促进硼烷（BH 3 ）的形成，随后硼烷充当真正的催化剂。这一发现促使我们探索这些意想不到的转变的未开发潜力，以期使用更具成本效益和环境友好的亲核预催化剂来简化硼氢化反应。通过计算研究，我们能够确定水实际上可以发挥这一作用。在此，我们报告了一项关于腈的简单硼氢化反应的研究，腈是一种众所周知的具有挑战性但具有合成价值的底物，仅使用水分作为活化剂。这种水分辅助的腈硼氢化工艺可以以一锅方式与一系列下游转化无缝集成，生产有价值的含氮产品，例如对称亚胺、硫脲和双（醇）胺以及N-杂环，例如吡咯、吡啶、吡啶鎓盐、2-亚氨基噻唑啉和咔唑。

  The Cu/ABNO-catalyzed aerobic oxidative coupling of diols and primary amines to access N-substituted pyrroles is highlighted (ABNO = 9-azabicyclo[3.3.1]nonane N-oxyl). The reaction proceeds at room temperature with an O2 balloon as the oxidant using commercially available materials as the substrates and catalysts. The catalyst system is characterized by a broad range of substrates and a good tolerance
