  • Intramolecular hydrogen bonding and its influence on conformation. Circular dichroism of chiral bilirubin analogs
    作者:Stefan E. Boiadjiev、David A. Lightner
    DOI:10.1016/s0957-4166(99)00254-2
    日期:1999.7
    Enantiopure synthetic bilirubin analogs with variously modified (e.g. alkyl for natural propionic acid or ester) C(8) and C(12) side chains and with but a single chiral center in either or both, exhibited exciton coupled circular dichroism (CD) spectra. The CD intensity is greater when the stereogenic center is in a propionic acid side chain than in an alkyl side chain. (C) 1999 Elsevier Science Ltd. All rights reserved.
  • Conformational control by remote stereogenic centers: linear tetrapyrroles
    作者:Stefan E. Boiadjiev、David A. Lightner
    DOI:10.1016/j.tetasy.2004.08.029
    日期:2004.10
    A novel, optically-active N-21-N-22, N-23-N-24 bis-carbonyl-bridged bilirubin congener 1 with propionic acids replaced by sec-butyls exhibits a strong negative exciton chirality circular dichroism spectrum from the (S,S)-enantiomer. Molecular dynamics calculations favor the M-helical diastercomer by 0.4 kJ/mol over the P. The dipyrrinone model 2 of one half of 1 exhibits an almost undetectable circular dichroism. Unlike 1, which is only very weakly fluorescent, 2 is strongly fluorescent, with quantum yield phi(F) similar to 0.70. (C) 2004 Elsevier Ltd. All rights reserved.
