  Synthesis and evaluation of 3-anilino-quinoxalinones as glycogen phosphorylase inhibitors

  摘要：

  A series of 3-anilino-quinoxalinones has been identified as a new class of glycogen phosphorylase inhibitors. The lead compound I was identified through high throughput screening as well as through pharmacophore-based electronic screening. Modifications were made to the scaffold of 1 to produce novel analogues, some of which are 25 times more potent than the lead compound. (c) 2005 Elsevier Ltd. All rights reserved.

  photoredox-catalysed chlorination of quinoxalin-2(1H)-ones was developed by using CHCl3 as a chlorine source, thus affording various 3-chloroquinoxalin-2(1H)-ones in moderate to high yields. This protocol is characterized by mild reaction conditions, excellent regioselectivity, and readily available chlorination agent. Considering the operational simplicity and low cost of this chlorination approach, this

  使用 CHCl 3作为氯源，开发了一种光氧化还原催化的 quinoxalin-2(1 H )-ones 氯化反应，从而以中等至高产率提供了各种 3-chloroquinoxalin-2(1 H )-ones。该方案的特点是反应条件温和、区域选择性好、氯化剂易得。考虑到这种氯化方法的操作简单性和低成本，这种开发的方法为将氯官能团快速结合到杂芳烃中提供了一种创新途径，并将激发更广泛地开发新的氯化策略。
