Abstract
The novel functionalized alkyl (Z)-2-(3-oxo-3,4-dihydroquinoxalin-2(1H)-ylidene)acetate, uracil, and thiocyanatomaleate derivatives have been prepared from substituted dihydroquinoxalines, benzylaminomaleates, and 6-amino-1,3-dimethylpyrimidine-2,4(1H,3H)-dione in the presence of N-thiocyanatosuccinimide intermediate generated from NH4SCN with NCS at room temperature, respectively. Convenient synthesis of sulfur-containing compounds of pyridinium ylide and S-aryl carbamimidothioate derivatives is described under catalyst-free condition in good yields.
