Synthesis, molecular and crystalline structure of 2-(alkylsulfanyl)-4-aryl(hetaryl)-5,6,7,8-tetrahydroquinoline-3-carbonitriles

[Figure not available: see fulltext.] 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. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
