CuI/N,N-Dimethylglycine-Catalyzed Coupling of Vinyl Halides with Amides or Carbamates
摘要:
The Cul-catalyzed coupling reaction of vinyl halides with amides or carbamates proceeds well at room temperature to 80 degreesC in dioxane to give enamides using NN-dimethylglycine as the promoter and Cs2CO3 as the base. The geometry of the C-C double bond is retained during the reaction course.
