摘要
以2-氯环己酮为原料,经亲核磺化、氯化和胺化3步反应合成了环己磺菌胺,总收率55.6%。中间体2-氧代环己基磺酸钠和环己磺菌胺的结构经核磁共振氢谱和碳谱确证。该工艺方法操作简单,反应条件温和。
Chesulfamide was obtained with a total yield of 55.6%through sequential nucleophilic sulfonylation,chloronation and amination of 2-chlorocyclohexanone.The structures of sodium 2-oxocyclohexane-1-sulfonate as a key intermediate and chesulamide were confirmed by IR,^(1)H and ^(13)C NMR spectra.This new process has advantages including easy operation and mild conditions.
