Synthesis of mono- and disubstituted 1H-imidazo[1,2-b]pyrazoles

Article abstract of DOI:10.1080/00397919908085772

The improved synthesis of 1H-imidazo[1,2-b]pyrazole 1 and of mono- and disubstituted derivatives is described and representative experimental procedures are given. Namely, 2-, 3-, 7- and 6-monosubstituted (2-15k), 2,3- and 6,7-disubstituted (16,17) compounds are prepared and characterized.
