functionalized α-ketoamide and α-ketotetrazole small-molecule peptidomimetic-like building blocks from prototypical synthons with two points of diversity. Incorporation of chalcone and alkynyl moieties with further ring-forming reactions enables access to additional novel heterocyclic ring systems, including a unique and potentially highly pharmacologically relevant scaffold, a 1,2-selenazol-3(2H)-one
描述了一种新的缩合后多组分反应(MCR)方法,该方法包括氧化脱
氨基,该氧化脱
氨能够通过两个步骤访问多个特权的含羰基支架。这些协议允许从具有两个多样性点的原型合成子轻松获得功能化的α-酮酰胺和α-酮咯唑小分子拟肽样构建基块。
查尔酮和炔基部分与进一步的成环反应的结合使得能够获得另外的新颖的杂环系统,包括独特的和潜在的与药理学相关性高的支架1,2-
硒代唑-3(2 H)-one。
