range of functional oxazolidinones is reported. The method is based on cheap and readily available starting materials including terminal and internal (bicyclic) epoxides and phenyl carbamate. The oxazolidinones serve as highly useful synthons for the high yield preparation of non‐symmetrical ureas by nucleophilic ring‐opening affording the targeted urea compounds with excellent functional group diversity
据报道,一种有效且实用的铝催化方法可用于一系列功能性恶唑烷酮。该方法基于便宜且容易获得的起始原料,包括末端和内部(双环)环氧化物和氨基甲酸苯酯。恶唑烷酮类化合物是非常有用的合成子,可通过亲核开环高产率制备非对称脲,为目标脲化合物提供了出色的官能团多样性,高区域选择性和高达> 99%的分离产率。
