An efficient microwave assisted synthesis of novel class of Rhodanine derivatives as potential HIV-1 and JSP-1 inhibitors

(Z)-5-(2-(1H-Indol-3-yl)-2-oxoethylidene)-3-phenyl-2-thioxothiazolidin-4-one (7a–q) derivatives have been synthesized by the condensation reaction of 3-phenyl-2-thioxothiazolidin-4-ones (3a–h) with suitably substituted 2-(1H-indol-3-yl)-2-oxoacetaldehyde (6a–d) under microwave condition. The thioxothiazolidine-4-ones were prepared from the corresponding aromatic amines (1a–e) and di-(carboxymethyl)-trithiocarbonyl (2). The aldehydes (6a–h) were synthesized from the corresponding acid chlorides (5a–d) using HSnBu3.
