Synthesis of pyrrolizines by intramolecular capture of 1,4-dipolar intermediates in reactions of enamines with dimethyl acetylenedicarboxylate [PDF]
, 1981 Solvent polarity and reaction temperature strongly influence the reactions of dimethyl acetylenedicar-boxylate (DMAD) with 1-pyrrolidinyl enamines of acyclic and cyclic ketones. Whereas DMAD and 1-[1-phenyl-2-(phenylthio)ethenyl]pyrrolidine (3) give only

Synthetic thiophenes induce chromosomal damage and trigger apoptosis in human cancer cell lines
European Journal of Medicinal Chemistry Reports, 2022 Thiophenes are heterocyclic compounds containing a five-membered ring with sulphur as the heteroatom. This class of substances has been shown to have several biological activities, including specific anti-proliferative effects against some cancer cell ...
