Abstract: Abstract New 2-substituted pyrazolo[5,1- b ][1,3]oxazoles are synthesized through the Sonogashira coupling reaction of 2-iodomethyl-6-methylpyrazolo[5,1- b ][1,3]oxazole with terminal alkynes in the presence of a palladium catalyst. This process is carried out in the absence… read more here.
