regioselective synthesis of 2,3,4-trisubstituted furans using AgNO3 catalyst from haloalkynes in a one-pot procedure has been reported. The transformation consists of a sequential silver-catalyzed nucleophilic addition and cyclization reaction of haloalkynes. A wide variety of haloalkynes can be used in this chemical process.
已经报道了使用一锅法从卤代炔烃中使用AgNO 3催化剂进行区域选择性合成2,3,4-三取代的呋喃。该转化由卤代炔烃的连续银催化亲核加成和环化反应组成。在该化学过程中可以使用各种各样的卤代炔烃。
