Copper(II)-catalyzed dehydrogenative cross-coupling between two azoles

The copper(II)-catalyzed dehydrogenative coupling between two different azoles for the preparation of unsymmetrical biazoles has been developed. The current catalytic system can effectively control the chemoselectivity for heterocoupling over homocoupling.

Palladium(II)-catalyzed oxidative C-H/C-H cross-coupling between two structurally similar azoles

Power of two: A widely functional-group tolerant, selective and rapid oxidative cross-coupling between two structurally similar azoles has been carried out by using a palladium/copper co-catalytic twofold C-H activation method (see scheme). Copyright

Copper as a powerful catalyst in the direct alkynylation of azoles

[Chemical equation presented] Copper-bottomed catalysis! The direct alkynylation of azoles through a copper-based C - H bond activation, using alkynylbromides as the coupling partner, has been developed (see scheme). The method is very rapid, is functional-group tolerant, and provides a straightforward entry to diverse alkynyl heterocycles that is complementry to the Sonogashira reaction.

Stereoselective direct copper-catalyzed alkenylation of oxazoles with bromoalkenes

(Chemical Equation Presented) A copper-catalyzed direct alkenylation of oxazoles with bromoalkenes has been developed. The method is both regio- and stereoselective and tolerates a variety of functional groups. A wide range of 2-E-vinyl-substituted oxazoles were obtained in high yields including the highly fluorescent alkaloid annuloline.
