Efficient kinetic resolution of amino acids catalyzed by lipase AS ‘Amano’ via cleavage of an amide bond
摘要:
Herein the efficient kinetic resolution of non-natural alpha-amino acids catalyzed by lipase AS 'Amano' via cleaving the amide bond is reported. The starting materials were the corresponding amino acid amides and the amino acids were generated with ees of up to 99% with E values of > 600. These results indicated that the lipase AS 'Amano' could be a powerful amide hydrolase for the kinetic resolution of amino acid starting from the corresponding amino acid amides.

the synthesis of α-amino acids via C-alkylation under basic conditions followed by hydrolysis/decarboxylation. In contrast, the C-arylation of this reagent remains undeveloped. Herein, we report a novel strategy for the synthesis of racemic α-arylglycines based on the selective arylation of DEAM with diaryliodonium salts under mild, transition metal-free conditions. The reaction features good functional
