A variety of oxazoles can efficiently be prepared, in a single step and in good yield, from primary amides and 1,2-dihaloalkenes using copper-catalysis. This new method allows the re-gioselective formation of a range of substituted oxazoles. The required 1,2-dihaloalkenes can prepared by simple treatment of alkynes with elemental bromine or iodine.
使用铜催化,伯酰胺和 1,2-二卤代烯烃可在一个步骤中以良好的收率有效地制备各种恶唑。这种新方法允许区域选择性地形成一系列取代的恶唑。所需的 1,2-二卤代烯烃可以通过用元素溴或碘对炔烃进行简单处理来制备。
