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.
An efficient and general palladium-catalyzedcoupling of 3-chloro-quinoxalinones with a variety of nitrogen-containingnucleophiles such as (hetero)aromatic and aliphatic amides as well as some challenging weakly nucleophilic nitrogen compounds including lactams, carbamates and NH-containing azoles is described. In all cases, the reactions take place rapidly and cleanly in dioxane using Pd(OAc)2 as
3-氯喹喔啉酮与各种含氮亲核试剂(如(杂)芳族和脂族酰胺)以及一些具有挑战性的弱亲核氮化合物(包括内酰胺,氨基甲酸酯和含NH的吡咯)的有效且通用的钯催化偶联是描述。在所有情况下,反应都会在二恶烷使用Pd(OAc)2作为催化剂,使用Xantphos作为配体,使用K 2 CO 3作为碱,可以很好地实现3- N-取代的喹喔啉酮类产品的偶联。
