CuI介导亚胺与2-碘代乙酸乙酯的Reformatsky反应合成β-氨基酯
CuI mediated synthesis of β-amino esters visa the Reformatsky reaction of imines with 2-iodoacetates
摘要
Abstract
Objective:To develop a simple and efficient cuprous iodide-mediated catalytic system of Reformatsky reaction.Methods:The Reformatsky reaction of ethyl iodoacetate 2a with imines 1 was efficiently catalyzed by zinc powder and mediated by the cheap and easily available cuprous iodide with acetonitrile/water mixed solvent as the reaction solvent.Results:The Reformatsky addition products β-amino esters 3 can be obtained with high yield(up to 95%)under mild conditions and the structures of products 3 were characterized by 1H NMR、13C NMR and HRMS.In addition,according to the previous research and the related literature,the possible reaction mechanism was proposed.Conclusion:Mediated by cuprous iodide,the Reformatsky reaction of ethyl iodoacetate 2a with imines 1 can be scaled up to the gram scale,which is conducive to industrial production.关键词
