✦ Synopsis

Complete

I3C NMR spectral assignments were made for wyosine, 4,9-dihydro-4,6-dimethyl-9-0~0-3-(p-~ribofuranosyl)imidazo[l,2-~]purine, a hpermodified, fluorescent nucleoside of transfer RNAs, and its isomers methylated at N-5 and at N-1. The influence of the position of N-methylation on the -C chemical shifts of the tricyclic nucleoside is discussed. In relation to the parent N-unsubstituted compound, the most pronounced changes of chemical sbifts appear in wyosbe. Chemical sbfi data for tbe sugar moiety suggest that the population of the anti conformer in wyosine is higher than in the other tricyclic nucleosides.
