A TBAI-catalyzed one-pot synthesis of cx-ketoamides via sp(3) C-H radical/radical cross-coupling and domino aerobic oxidation was developed. This synthesis is suitable for abroad range of substrates. The control experiments suggested a possible oxidative coupling mechanism. (C) 2015 Elsevier Ltd. All rights reserved.

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
