Synthesis and Antimicrobial of Certain New Thiazolidinone, Thiazoline, and Thiophene Derivatives

摘要

2-Cyano-N-(9,10-dioxo-9,10-dihydro-anthracen-2-yl)-acetamide (1) was utilized as a key intermediate for the synthesis of thiazolidin-4-one 2 and thiocarbamoyl 5 derivatives via reaction with 2-sulfanylacetic acid and phenyl isothiocyanate, respectively. Compound 5 reacted with different α-halo compounds to give thiazolidin-5-one 4, thiazolidine 7a,b, thiazolidin-4-one 8, and thiophene derivatives 10a,b. Thiazoline 6 and tetrahydro-benzothiophene 12 derivatives were obtained via a one-pot reaction of compound 1 with phenyl isothiocyanate/sulfur and cyclohexanone/sulfur, respectively. Representative compounds of the synthesized products were evaluated as antimicrobial agents. Some of these compounds exhibited promising activities.Supplemental materials are available for this article.
