Regioselective Cyclocondensations of Chlorocarbonylsulfenyl Chloride with Hydrazones: Effective Synthesis of a Class of Sulfur and Nitrogen Containing Heterocycles with -COS- Linkage
摘要:
Regioselective cyclocondensations of several hydrazones with chlorocarbonylsulfenyl chloride afforded 1,3,4-(3H,6H)-thiadiazin-2-one derivatives and 3(2H)-(dimethylamino)thiazolones. The -COS- linkage was effectively incorporated into the S,N-containing heterocycles.
