摘要

Abstract Cyclopentylidene-and cyclohexylidene (cyano) acetamides reacted with malononitrile and cyano-(thioacetamide) according to the Michael pattern with exchange of the methylene components to give substituted 1-amino-2, 6, 6-tricyano-1, 3-cyclohexadienes and thieno [2, 3-d] pyrimidine-4 (3 H)-thiones. Condensation of cyclopentylidene-and cyclohexylidene (cyano) acetamide with 1, 3-dicarbonyl compounds afforded 4, 6-di- ...
