Nickel-catalyzed synthesis of oxazoles via C-S activation
The synthesis of 2-substituted oxazoles is achieved via nickel-catalyzed cross-coupling reaction of 2-methylthio-oxazole and various organozinc reagents. An extension of this method is demonstrated with a chemoselective, one-pot synthesis of unsymmetrical

Diheteroarylmethanes. 5. E-Z isomerism of carbanions substituted by 1,3-Azoles: 13C and 15N π-charge/shift relationships as source for mapping charge and ranking the electron-withdrawing power of heterocycles
Previously proposed π-charge/shift relationships have been applied to 13C and 15N shifts of the carbanions of 2-benzylazoles (thiazole, oxazole, and imidazole), their corresponding benzo-fused analogs, and bis(2-azolyl)methanes (azol
