Abstract
Here we report a greener approach for the synthesis of enamines from enols of 1,3-alkyl-2-
thioxodihydropyrimidine-4,6(1H,5H)-dione (thiobarbituric acid) acid using ammonium chloride and
ethanol as solvents. This protocol removes the need for catalysts or harsh conditions.

Abstract
Reactions of secondary amides 2a-i with 1-chloro-1H-benzotriazole and triphenylphosphine give imidoylbenzotriazoles 3a-i. The treatment of 3a,b,e,g with silyl enol ethers 5a,b in the presence of potassium tert-butoxide provides a new general approach to enaminoketones 6a-h.
