A Cu(I)-catalysed Sonogashira-type cross coupling reaction with aliphatic or aromatic bromoisoxazolines or N-alkoxyimidoyl bromides and alkynes is reported. The protocol we developed employs catalytic amount of copper(I), non-toxic ligand bathophenanthroline and is tolerant to a wide range of functional groups and is therefore particulary adapted in the context of drug discovery.
