Chiral Di (N-protected a-amino)-b-diketones and its transition metal complexes have been synthesized. Di(N-protected a-amino)-b- diketones were prepared by reaction of activation of N-protected- a-amino acids (imidazolide) with a-diazoketones derived from natural amino acids in presence of lithium diisopropyl amid in tetrahydrofuran as a solvent at -78 °C and treatment the product with rhodium acetate to remove diazo group. The synthesized compounds were characterized by analytical techniques viz: IR, NMR and elemental analysis. The thermal stability of the newly synthesized metal complexes have been studied.

Di(N-protected-α-amino)diazo-β-diketones were prepared by the reaction of activated N-protected-α-amino acids (imidazolides) with α-diazoketones, derived from natural amino acids, in the presence of lithium diisopropylamide in tetrahydrofuran as the solvent at -78 °C.
Chiral imidazole derivatives synthesis from enantiopure N-protected α-amino acids
Bures, Filip,Kulhanek, Jiri
, p. 1347 - 1354 (2007/10/03)
A route to the preparation of enantiopure ligands based on a 2-phenylimidazol ring is described. The stereogenic centre is placed into the chain bonded to the fourth carbon of the imidazole ring. The synthesis starts from inexpensive and readily available
