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

Two sides to the story: Neooxazolomycin, a member of the oxazolomycin family of antibiotics, was synthesized in naturally occurring form by a convergent approach. This highly stereoselective strategy consists of a Tamao hydrosilylation, palladium-catalyzed enolate alkenylation, dihydroxylation accompanied by lactonization, and a Nozaki-Hiyama-Kishi reaction to construct the right-hand segment as well as an improved route to the left-hand segment. (Chemical Equation Presented).
