The condensation of an .alpha.-halogen carbonyl compound with carbamic acid esters in the presence of a basic condensing agent and an aprotic solvent enables the production of oxazolinone-2-compounds in a high degree of purity, and in high yields in one step by using simple and readily available starting compounds.
在碱性缩合剂和无极溶剂的存在下,α-卤代酰基化合物与氨基甲酸酯的缩合反应,使得可以使用简单易得的起始化合物,在一步反应中高产量高纯度地合成噁唑烷酮-2化合物。
