Abstract: Abstract A copper-catalyzed formal propargylic [3 + 2] cycloaddition between propargylic acetates and 3-(2-tosylhydrazono)propanoates for the synthesis of (E)-β-substituted-β-pyrazolylacrylates has been realized. The reaction showed broad substrate scope and excellent stereoselectivities, thus leading to a variety of… read more here.
