Revised carbon-13 chemcial shift assignments are reported for the cytokinins (1'R)-1'-methylzeatin [(1'R)-1] and its 9-β-D-ribofuranoside [(1"R)-2]. Previous shift assignments for the two methyl carbons in the purine N6 side chain of (1'R)-1 and (1"R)-2, as well as those for the C(2') and C(3') carbons of (1"R)-2, have now been reversed by comparison with the 13C nmr data for the diastereomeric nucleoside (1"S)-2 and the cis isomers 3 and 4.

Abstract

Revised carbon-13 chemcial shift assignments are reported for the cytokinins (1'R)-1'-methylzeatin [(1'R)-1] and its 9-β-D-ribofuranoside [(1"R)-2]. Previous shift assignments for the two methyl carbons in the purine N6 side chain of (1'R)-1 and (1"R)-2, as well as those for the C(2') and C(3') carbons of (1"R)-2, have now been reversed by comparison with the 13C nmr data for the diastereomeric nucleoside (1"S)-2 and the cis isomers 3 and 4.
