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 2,5-disubstituted oxazoles. This synthesis of 2- and 2,5-substituted oxazoles using this method provides great advantages over previous methods for
2-取代的恶唑的合成是通过镍催化的2-甲硫基恶唑与各种有机锌试剂的交叉偶联反应而完成的。不对称的2,5-二取代的恶唑的化学选择性,一锅法合成证明了该方法的扩展。用这种方法合成2-和2,5-取代的恶唑相对于这些化合物的先前方法提供了很大的优势,并且与当前的环脱水策略高度互补。
