Abstract
The 1J(CH) coupling constant of C-1 in nucleosides is increased compared to those of the other carbons of the sugar moiety. Applying this to several D-ribonucleosides the signals C-4′/C-1′of these a-anomers are reversed to those of the 8-counterparts (C-1′/C-4′). This phenomenon and the broadening of the C-3′ signal compared to that of C-2′ establishes the seauence C-4′,1′,2′,3′,5′ (increasing field) for a number of α-D-ribonucleosides.This publication has 7 references indexed in Scilit:
