Synthesis and alkylation of 1-substituted 3-thioxo-2,3,5,6,7,8-hexahydroisoquinoline-4-carbonitriles
摘要:
The condensation of cyclohexylidene(cyano)thioacetamides with aldehydes or of 2-acyl-1-(morpholin-4-yl)cycloalkenes with dithiomalonamide gave 1-alkyl(aryl)-3-thioxo-2,3,5,6,7,8-hexahydroisoquinoline-4-carbonitriles. Reactions of the latter with various alkylating agents selectively produced the corresponding isoquinolin-3-yl sulfides or products of their subsequent Thorpe cyclization, thieno[2,3-c]isoquinolines.
