Synthesis and anti‐HIV activity of substituted 1,2,4‐triazolo‐thiophene derivatives

A new series of substituted 1,2,4‐triazoles bearing thiophene molecules 8 and 10 has been synthesized from cycloaddition of thiophene 3‐and 2‐carbonitriles 5 and 9 , respectively, with the reactive cumulene intermediates 4 . The newly synthesized products have been evaluated for their anti‐HIV activity. © 2007 Wiley Periodicals, Inc.
