The cobalt-catalyzed cross-dehydrogenative coupling of (benz)oxazoles and ethers is described. Access to some important bioactive heteroaryl ether derivatives was achieved using CoCO3 as an inexpensive catalyst at levels as low as 1.0 mol %. In

Presented herein is a new complexity-generating method in which both functionalities of α-imino esters undergo stereoselective cyclization with isocyanoacetates to produce directly linked oxazole-imidazolines, which can be transformed into highly functionalized α,β-diamino esters and imidazolinium salts in high diastereo- and enantiopurity. Double up: An unprecedented silver-catalyzed title reaction has been developed and provides access to directly linked oxazole-imidazolines. A highly diastereo- and enantioselective variant was also realized using the catalyst Ag/L*. The products can be easily transformed into highly functionalized chiral α,β-diamino esters or imidazolinium salts which are useful motifs in asymmetric synthesis and catalysis.

The direct decarboxylative arylation of hetereoarenes with benzoic acids through a nickel-catalyzed sp2 C-H functionalization process was developed. This process provides the first examples of decarboxylative cross-coupling reactions with aroma
