Novel selected tandem transformations of the amino and carbonyl/nitrile groups in the gewald thiophenes
Novel transformations of the amino and carbonyl/nitrile groups in the Gewald thiophenes were studied for thienopyrimidine synthesis. It was found that 2-amino-thiophene-3-carboxamides and ethyl 2-(acetylamino)-4,5,6,7-tetrahydro- 1-benzothiophene-3-carbo-

Synthesis of 5H-Triazolo- and 5H-Tetrazolothieno-1,4-diazepin-6(7H)-ones
5H-Triazolo- and 5H-tetrazolothieno-1,4-diazepin-6(7H)-ones have been obtained by the base catalysed ring expansion reaction of 5-chloromethyl-1,2,4-triazolo- and 5-chloromethyltetrazolothienopyrimidines.The requi
