[Figure not available: see fulltext.] The multicomponent condensation of malononitrile, hydrogen sulfide, aldehydes, 1-(cyclopent-1-en-1-yl)pyrrolidine, and alkylating agents leads to the formation of 6,7-dihydro-5H-cyclopenta[b]pyridine derivatives. The structure of a number of heterocycles obtained on their basis was studied by X-ray structural analysis. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
