Ethyl 3- and 5-triflyloxy-1H-pyrazole-4-carboxylates in the synthesis of condensed pyrazoles by Pd-catalysed cross-coupling reactions

The easily obtainable title compounds ethyl 5- and 3-triflyloxy-1H- pyrazole-4-carboxylates (2 and 5) have been used as precursors in Sonogashira-type cross-coupling reactions with various alkynes to obtain the corresponding 5- and 3-alkynyl-4-(ethoxycarb
