Synthesis, molecular and crystalline structure of 2-(alkylsulfanyl)-4-aryl(hetaryl)-5,6,7,8-tetrahydroquinoline-3-carbonitriles
The multicomponent reaction of aromatic and heteroaromatic aldehydes, malonodithioamide, 1-(cyclohex-1-en-1-yl)piperidine, and alkylating reagents was studied. A wide range of new 2-(alkylsulfanyl)-4-aryl(hetaryl)-5,6,7,8-tetrahydroquinoline-3-carbonitriles were synthesized, and their molecular and crystalline structures were studied by X-ray structural analysis.
