© 2021, Pleiades Publishing, Ltd.Abstract: 2,3-Dialkynylthiophene derivatives were synthesized by using regio- andstereocontrolled Pd-catalyzed Sonogashira coupling and desilylation reactions.The synthesized compounds were analyzed in silico for their pharmacokineticparameters, general toxicity, and drug scores. In particular,3-ethynyl-2-(phenylethynyl)thiophene and3-ethynyl-2-[(4-methylphenyl)ethynyl]thiophene were found to have relativelyhigh drug scores and low toxicities. The antioxidant activity of the titlecompounds were evaluated by five different assays.3-Ethynyl-2-(naphthalen-1-ylethynyl)thiophene displayed significant reducing andfree radical scavenging activities.
