Abstract
2-(5,10-Dioxo-1,4-dipheny1-3,4-dihydrobenzo[g]quinoxalin-2(1H,5H, 10H)-ylidenOhydrazinecarbothioamide (4) and 244-oxothiazolidin-2-ylidene)hydrazono)-1,4-dipheny1-1,2,3,4-tetrahydrobenzo[g]quinoxaline-5,10-dione (5), were prepared and utilized as versatile building blocks, via incorporating in series of conversions including cyclocondensation reactions to afford a series of four and five pharmacophoric motif conjugates 10, 13, 18, 20, 21, 25, 30, 31, 32, 33 and 34 in fair yields.
