The reaction of 3,3-diaminoacrylonitriles with DMAD and 1,2-dibenzoylacetylene was studied. It is shown that the direction of the reaction depends on the structure both of acetylene and of diaminoacrylonitrile. In the reaction of DMAD with acrylonitr

The reaction of 2-azidobenzaldehydes with 2-thioamides of cyanoacetic acid proceeds without a solvent and base at 80–90°C selectively by one of the possible routes to form tetrazolo[1,5-a]quinolines. The proposed mechanism of the reaction involves

A design and a convenient approach for the synthesis of novel N-sulfonyl-2-diphenylmethylsulfinylacetamidines have been demonstrated by starting from benzhydrylsulfanylacetic (BSA) acid. This approach involves a sequential amidation with amines, thio
