STEREOELECTRONIC EFFECTS OF MODIFIED PURINES ON THE SUGAR CONFORMATION OF NUCLEOSIDES AND FLUORESCENCE PROPERTIES

Abstract Conformational analyses of the sugar moieties of a series base-modified purine-2′-deoxynucleosides on the basis of vicinal [1H,1H] coupling constants is presented (PSEUROT 6.2) Fluorescence data of several 7-deaza- and 8-azapurine 2′-deoxynucleosides are given.
