Abstract Cyanoselenoacetamide reacts with hydrogen sulfide to form propane-bis (thioamide), which can be used to produce thiazoles (the Hantzsch synthesis) and 3-thioxo- 1-phenyl-2, 3, 5, 6, 7, 8-hexahydroisoquinoline-4-carbonitrile. From the latter compound, 2- alkylsulfanyl-1-phenyl-5, 6, 7, 8-tetrahydroisoquinoline-4-carbonitriles and 1-amino-N-(4- bromophenyl)-5-phenyl-6, 7, 8, 9-tetrahydrothieno [2, 3-c] isoquinoline-2-carboxamide ...
