In our previous work, a glucose-fipronil (GTF) conjugate at the C-1 position was synthesized via click chemistry and a glucose moiety converted a non-phloem-mobile insecticide fipronil into a moderately phloem-mobile insecticide. In the present paper, fipronil was introduced into the C-2, C-3, C-4, and C-6 positions of glucose via click chemistry to obtain four new conjugates and to evaluate the effects of the different glucose isomers on phloem mobility. The phloem mobility of the four new synthetic conjugates and GTF was tested using the Ricinus seedling system. The results confirmed that conjugation of glucose at different positions has a significant influence on the phloem mobility of GTF conjugates.

Acetylated 6-chloro-, 6-bromo-, 6-iodo-, and 6-azido-6-deoxy-α-D-glucopyranosyl azides (26, 22, 17, 30), -β-D-glucopyranosyl azides (27, 23, 18, 31), -α-D-galactopyranosyl azides (28, 24, 19, 32), and -β-D-galactopyranosyl azides (29, 25, 20, 33) have been obtained by nucleophilic displacement reactions of the appropriate 6-O-(p-toluenesulfonates) 9-12.Hydrogen iodide elimination from the 6-iodo-6-deoxyglycosyl azides 17-20 by DBU or DBN leads to the hex-5-enopyranosyl azides with α-D-xylo (43), β-D-xylo (44), α-L-arabino (46), and β-L-arabino configuration.The. structures, anomeric configurations, and conformations of the products were determined by 1H-NMR spectroscopy
