Metal-free, organocatalytic cascade formation of C–N and C–O bonds through dual sp<sup>3</sup>C–H activation: oxidative synthesis of oxazole derivatives
An organocatalytic cascade reaction that involves the formation of C-N, C-O and C=N bonds in one process via dual sp(3) C-H activation has been developed. This protocol affords a facile metal-free methodology for the synthesis of oxazole derivatives in air under mild conditions.

A highly efficient synthesis of polysubstituted oxazoles was developed via a copper-catalyzed tandem oxidative cyclization. The desired products can be obtained from readily available starting materials under mild conditions. This is an attractive alternative method for the synthesis of oxazole derivatives.
