A novel and straightforward synthetic protocol was developed to synthesize 2-dialkylamino-2-oxazolin-4-ones from various Vilsmeier salts and α-hydroxy amides derivatives. Notably, thozalinone (3a), as a mild stimulant in tristimania and anorexic, could be synthesized simply and in a high yield using this methodology.
本研究开发了一种新颖而简单的合成方法,可从各种维尔斯梅尔盐和α-羟基酰胺衍生物中合成 2-二烷基氨基-2-恶唑啉-4-酮。值得注意的是,噻嗪酮(3a)是一种用于治疗三联症和厌食症的温和兴奋剂,采用这种方法可以简单、高产地合成。
