C–H dithiocarbonation of quinoline N-oxides with various potassium O-alkyl xanthates. The reaction performed well under transition-metal-free, base-free, and room-temperature conditions with wide substrate tolerance. Employing potassium O-tert-butyl xanthate (tBuOCS2K) as a nucleophile, some valuable quinoline-2-thiones were unexpectedly obtained in a one-pot reaction without any additional base.
通过 Ts 2 O 促进的喹啉 N-氧化物与各种 O-烷基黄原酸钾的脱氧 C-H 二硫代碳酸化反应,开发了一种简单、有效且实用的合成 S-喹啉黄原酸的方法。该反应在无过渡金属、无碱和室温条件下表现良好,具有广泛的底物耐受性。使用O-叔丁基黄原酸钾( t BuOCS 2 K)作为亲核试剂,在没有任何额外碱的情况下,在一锅反应中意外地获得了一些有价值的喹啉-2-硫酮。
