Benzylation of pyrrolo[2,1-a]isoquinoline derivatives has been realized with various phenols by the use of ammonium acetate as a promoter (20 examples, up to 84% yield). DMSO served as the source of methylene and solvent. The employment of iron chloride as a catalyst can also afford the desired benzylated products in moderate to good yields (11 examples, up to a 74% yield).
通过使用乙酸铵作为促进剂,吡咯并[2,1- a ]异喹啉衍生物的苄基化已经与各种酚实现了(20个实例,产率高达84%)。DMSO 用作亚甲基和溶剂的来源。使用氯化铁作为催化剂也可以以中等至良好的产率提供所需的苄基化产物(11个实例,产率高达74%)。
