The nBu4NI-catalyzed sequential C–O and C–N bond formation via multiple sp3C–H bond activation of ethylarenes, using N,N-dialkylformamide as the amino source, provided α-ketoamides with moderate yields.
所述Ñ卜4 NI -催化的顺序C-O和C-N键的形成通过多个SP 3 C-H键活化ethylarenes,采用Ñ,Ñ -dialkylformamide作为氨基源,提供α酮酰胺具有中等产率。
Highly Enantioselective Synthesis of N‐Unprotected Unnatural α‐Amino Acid Derivatives by Ruthenium‐Catalyzed Direct Asymmetric Reductive Amination
An unprecedented Ru-catalyzed directasymmetric reductive amination of α-keto amides with ammonium salts has been achieved. This protocol provides an efficient and practical way for the synthesis of diverse enantioenriched α-aryl- or alkyl-substituted N-unprotected unnatural α-amino acids and N-unprotected β-branched α-amino acids. Further follow-up transformations enable access to drug intermediates
