Synthesis of acylamino acid esters of nucleoside 5'-phosphates and their investigation with PMR and CD spectra
Institute of Molecular Biology of the USSR Academy of Sciences Vavilov str., 32, Moscow 117312, USSR
Received April 14, 1977. The acylemino acid esters of nucleoside 5'-phosphates are synthesized via condensation of N-(N'-acylaainoacyl)imidazoles with nucleoside 5'-phosphates. The PMR and CD spectra of the esters obtained are studied. The 3'-isomers of the substances under study are observed to have a shift in the conformational N=S equilibrium of the carbobydrate moiety in favour of the S-form as compared to the initial nucleosides and their 2'-acyl esters.
