Rearrangement studies on 1-tetralylidenecyanothioacetamide: A different novel synthetic routes to strong fluorescent phenanthridine and phenanthrene analogues

Synthesis and domino reactions of polymethylene‐3‐cyanopyridine‐2(1Н)‐thiones

“…[7,8,[23][24][25] In order to unambiguously establish the structures of products of these reactions, we synthesized adamantyl derivative 12 (Scheme 3) and studied it using X-ray diffraction analysis.

Synthesis of Some New Pyridines, Thienopyridines and Pyrido[2,3:4′,5′]thieno[3′,2′‐d]pyrimidin‐8‐ones from 2‐Acetylbenzoimidazole.

“…Thin layer chromatogra- phy was carried out on 5´20 cm plates coated with silica gel GF 254 type 60, mesh size 50-250. Compounds 1 (8) and 2 (9,10) were prepared according to the reported method.…”

Novel Synthesis of N-Amino-2-Pyridones and Cycloalkane Ringfused Pyridines Containing Benzothiazole Moiety

“…Continuing our interest in development of efficient and simple procedures for the synthesis of fused heterocyclic nitrogen compounds [1][2][3][4][5] , We have previously reported several new approaches for the synthesis of condensed heterocycles utilizing 2-substituted methyl benzothiazole derivatives as starting materials [6][7][8][9] . As an extension of this work , we report in this paper a new one step synthesis of N-amino-2-pyridones and cycloalkane ring fused pyridine derivatives containing benzothiazole moiety from the reaction of 2-(benzothiazol-2-yl)-arylidenemethylcarbonitriles 3 10 with cyanoacethydrazide and cycloalkanones, respectively .…”
