A divergent approach has been successfully developed for the synthesis of N-1,2,4-oxadiazole substituted sulfoximines starting from N-cyano sulfoximines. This method has a wide degree of substrate scope that includes aryl, heteroaryl, alkyl, fluoroalkyl and saturated heterocyclic compounds. Excellent functional group tolerability was also observed. Extension of this methodology to nucleosides, amino
从N-氰基亚砜亚胺开始,已经成功地开发出一种用于合成N-1,2,4-恶二唑取代的亚砜亚胺的方法。该方法具有广泛的底物范围,包括芳基,杂芳基,烷基,氟代烷基和饱和杂环化合物。还观察到优异的官能团耐受性。已发现将该方法扩展至核苷,氨基酸和二肽是成功的。还建立了克级反应。该方法的主要部分是不含金属的,使用环境友好的溶剂(例如2-甲基THF和离子液体)是一个额外的优势。
