参考标题:Practical And Modular Construction Of C(Sp3)-Rich Alkyl Boron Compounds 作者:Yangyang Yang,Jet Tsien,Ayala Ben David,Jonathan M. E. Hughes,Rohan R. Merchant,Tian Qin |发布日期:2021.1.13 摘要:Alkyl Boronic Acids And Esters Play An Important Role In The Synthesis Of C(Sp3)-Rich Medicines, Agrochemicals, And Material Chemistry. This Work Describes A New Type Of Transition-Metal-Free Mediated Transformation To Enable The Construction Of C(Sp3)-Rich And Sterically Hindered Alkyl Boron Reagents In A Practical And Modular Manner. The Broad Generality And Functional Group Tolerance Of This Method
