Ibrahem, Ismail,Zou, Weibiao,Engqvist, Magnus,Xu, Yongmei,Cordova, Armando
, p. 7024 - 7029 (2005)
The direct three-component asymmetric Mannich reaction catalyzed by acyclic chiral amines or amino acids is presented. Simple acyclic chiral amines and amino acids - such as alanine-tetrazole (9), alanine, valine, and serine - catalyzed the three-componen

Zoete, M. C. de,Ouwehand, A. A.,Rantwijk, F. van,Sheldon, R. A.
, p. 171 - 174 (1995)
The ammoniolysis of amino acid esters and their derivatives was performed with lipases and proteases yielding the corresponding amino acid amides with moderate to high enantioselectivity.Phenylglycine methyl ester racemized slowly under the reaction conditions.

8-Aminoquinoline (AQ) is a widely used bidentate auxiliary in metal-catalyzed directed C-H functionalization reactions. Herein, we report an efficient and chemoselective method to convert various N-quinolyl carboxamides to primary amides with the treatment of a stoichiometric amount of 2-iodoxybenzoic acid oxidant or the combination of a catalytic amount of 2-iodobenzoic acid and Oxone co-oxidant in mixed solvents of H2O and HFIP. Its unique compatibility with the Phth-protected α-amino acid (αAA) substrates enhances the overall synthetic utility of the AQ-directed palladium-catalyzed C-H functionalization strategy for synthesis of complex αAAs.
