Synthesis, Spectroscopic Analysis, and In-Vitro Antimicrobial Evaluation of some Tetrahydrobenzo[a]Xanthene-11-Thiones

A. Sethukumar; Chandran Udhaya Kumar; Balasubramaniyam Arul Prakasam

Abstract A series of 12-aryl-8,9,10,12-tetrahydrobenzo[a]xanthene-11-thiones were synthesized by the reaction of substituted 12-aryl-8,9,10,12-tetrahydrobenzo[a]xanthene-11-ones with Lawessons Reagent in toluene under standard reaction conditions. All synthesized compounds were characterized by IR, NMR (1H and 13C), and mass spectra. Moreover, 2D-NMR (HOMOCOSY, HSQC, and HMBC) studies were also performed for compound 10b. The synthesized compounds were also screened for their antibacterial activities. [Supplementary materials are available for this article.
