Spectroscopic and Theoretical Study of Asymmetric 1,1′-Diaminoferrocene Conjugates of α-Amino Acids
摘要:
The synthesis and characterization of asymmetric 1,1'-diaminoferrocene conjugates of alpha-amino acids Boe-AA-NH-Fn-NH-Ac [AA = Gly (10), Ala (11), D-Ala (12), Val (13), Fn = 1,1'-ferrocenediyl] is reported. The conformational preferences of these organometallic peptidomimetics in solution are determined experimentally by circular dichroism spectroscopy, IR spectroscopy, and NMR spectroscopy and corroborated theoretically by DFT calculations.
