Synthetic transformations of higher terpenoids: XXXVI. Synthesis of furanolabdanoid glycoconjugates with a 1,2,3-triazole linker

详细

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 α-D-glucose, D-galactose, D-xylose, and L-arabinose afforded the corresponding N-glycosyl-1,2,3-triazole conjugates.
