A powerful three-component reaction for the synthesis of bicyclicthiazolidinethiones and oxazolidinones at room temp. in water, starting from readily available amines, chloroacetaldehyde, and CS2/CO2, is described. A simple one-pot procedure allows the construction of two new cyclic systems and four new bonds, with all reactants being efficiently utilized in this transformation. KHCO3 is used as a
用于在室温下合成双环噻唑烷硫酮和恶唑烷酮的强大三组分反应。描述了在水中,从容易获得的胺、氯乙醛和 CS2/CO2 开始。一个简单的一锅程序允许构建两个新的循环系统和四个新的键,所有反应物都在此转化中得到有效利用。KHCO3 用作 CO2 的生产源。证明了衍生化的广泛潜力。
