In addition, N-15 NMR chemical shifts for selected derivatives were investigated by using H-1-N-15 chemical shift correlation techniques. To map the influence of sugar moiety on the directly bonded nitrogen atom, selected N-9-glucosides and their ribose analogs were compared. Characteristic long-range H-1-N-15 coupling constants, measured by using H-1-N-15 gradient-selected single-quantum multiple bond correlation (GSQMBC), are also reported and discussed. All compounds investigated here belong to cytokinins, an important group of plant hormones.
