Procedures have been developed for the synthesis of 16-[(propargyloxy) methyl]- and 7- and 18-(propargyloxy) labda-8(9), 13,14-trienes from phlomisoic acid. Copper-catalyzed cycloaddition of the labdanoid alkynes to azido derivatives of alpha-D-glucose, D-galactose, D-xylose, and L-arabinose afforded the corresponding N-glycosyl-1,2,3- triazole conjugates.
