Carbonyldiimidazole (CDI) mediated synthesis of Nα- protected amino acid azides: Application to the one-pot preparation of ureidopeptides
Vasantha,Vishwanatha,Sureshbabu, Vommina V.
experimental part, p. 1093 - 1098 (2012/06/01)
Synthesis of Nα-protected amino acyl azides starting from corresponding acids via the carbonyldiimidazole (CDI) activation is described. The protocol is extended for a one-pot preparation of ureido peptides that circumvents the isolation of acy

, p. 1427 - 1431 (2007/10/03)
An efficient preparation of (S)-γ-isopropyl-α-methyl-β-tetramic acid has been established, and the α nucleophilicity of the acid has been also examined.
Enantioselective and diastereoselective formation of syn-3-hydroxy-4-amino acids (syn-statines) via tetramic acids

, p. 216 - 220 (2007/10/02)
Enantiomerically pure pyrrolidine-2,4-diones (tetramic acids) which can be diastereoselectively hydrogenated to syn-statines (4-amino-3-hydroxy-6-methylheptanoic acids) have been prepared by catalytic hydrogenation of 4-(benzyloxycarbonylamino)-3-oxocarboxylic acid esters.
