参考标题:Synthesis Of 1,2-Amino Alcohols Via Catalytic C-H Amidation Of Sp3 Methyl C-H Bonds 作者:Taek Kang,Heejeong Kim,Jeung Gon Kim,Sukbok Chang 摘要:Herein A New Synthetic Route To 1,2-Amino Alcohols Is Presented By Using C-H Amidation Of Sp(3) Methyl C-H Bonds As A Key Step. Readily Available Alcohols Were Employed As Starting Materials After Converting Them To Removable Ketoxime Chelating Groups. Iridium Catalysts Were Found To Be Effective For The C-H Amidation, And Lah Reduction Was Then Used To Furnish Beta-Amino Alcohol Products.
