Benzyloxazolidine-2,4-diones as potent hypoglycemic agents
摘要:
A series of benzyloxazolidine-2,4-diones, containing oxazole-based side chains, were found to lower blood glucose levels in the genetically obese ob/ob mouse. Incorporation of a benzofuran structural element in these compounds provides greatly enhanced in vivo potency. The syntheses and structure-activity relationships for this series are detailed.
The use of Ph3P/DDQ offers a novel, neutral and highlyefficient method for the efficient conversion of 2-hydroxyaryl aldoximes and ketoximes to 1,2-benzisoxazoles in excellent yields at room temperature.
Ph 3 P / DDQ的使用提供了一种新颖,中性和高效的方法,可在室温下以优异的收率将2-羟基芳基醛肟和酮肟有效转化为1,2-苯并恶唑。

and eco-friendly visible-light-induced protocol for the hydroacylation of quinones with α-ketoacids has been developed. In the absence of any catalyst or additive, the decarboxylative hydroacylation proceeded smoothly under visible-light irradiation at room temperature. A wide range of quinones and α-ketoacids were well-tolerated and afforded hydroacylation products up to 88% isolated yield. The reaction
