Facile synthesis of 6-aryl-3-cyanopyridine-2-(1H)-thiones from aryl ketones

Zheng, Ren-Lin,Zeng, Xiu-Xiu,He, Hai-Yun,He, Jun,Yang, Sheng-Yong,Yu, Luo-Ting,Yang, Li

, p. 1521 - 1531 (2012/04/17)

An improved synthesis of 6-aryl-3-cyanopyridine-2-(1H)-thiones utilizing enaminones as starting materials catalyzed by 1,4-diazabicyclo[2.2.2]octane (DABCO) was described. Moreover, a convenient one-pot conversion of aryl ketones to 6-aryl-3-cyanopyridine-2-(1H)-thiones was also developed in moderate to good yields (up to 80%). Copyright Taylor & Francis Group, LLC.
