REACTION OF 2-THIAZOLINE-2-THIOL WITH ISATIN DERIVATIVES
摘要:
The reaction of indol-2,3-dione derivatives with 2-thiazoline-2-thiol under thermal as well as photochemical conditions is described. Under refluxing ethanol it afforded 3,4'-dihydro-3-[2'-mercaptothiazolidine]indol-2-one. UV light-induced irradiation produced isomeric 2,4-dihydro-2[2'-mercapto- thiazolidine]indol-3-one and 2-mercapto-thiazolo[5,4-b]quinoline-4-carboxylic acid. The synthesized compounds were characterized by elemental analyses and spectral studies and were screened for antimicrobial activity.
