Abstract Polystyrene-supported vinyl sulfone reagent has been developed and used for solid-phase organic synthesis of 3-monosubstituted isoxazoles by 1,3-dipolar cycloaddition reaction with nitrile oxides and subsequent cleavage from the polymer support through an elimination reaction in the presence of potassium tert-butoxide. The advantages of this method include straightforward operation, good yield
摘要 聚苯乙烯负载的乙烯基砜试剂已被开发并用于固相有机合成 3-单取代异恶唑,通过与腈氧化物的 1,3-偶极环加成反应,然后在钾存在下通过消除反应从聚合物载体上裂解。叔丁醇。该方法的优点是操作简单、收率好、粗品纯度高。图形概要
