C-Alkylation and N-Acylation of 4-Amino-1-azabutadiene Derivatives. A Convenient Route to Monoalkylated 1,3-Diketones

Alkylation of 4-amino-1-azabutadiene derivatives 1 with different alkyl halides followed by acid hydrolysis gives mono-C-alkylated 1,3-diketones 3 in excellent yields.In contrast acylation of 1 occurs at the imine nitrogen.

An Unambiguous Synthesis of Pyrazoles by Sulphur Extrusion from 1,2,6-Thiadiazines

Di-imines (1) react with thionyl chloride and sulphur monochloride and dichloride giving different 1,2,6-thiadiazine S-oxides (3) and 1,2,6-thiadiazines (4), respectively.These last two compounds lead, by heating, to pyrazoles (6) via thermal extrusion of
