The synthesis of N,N’-diacetyl-β-chitobiosyl N-glycooxazoline 2 was investigated. A routine method was used
to prepare the N-benzyloxycarbonyl (Cbz) protected trichloroacetimidate donors 11 and 13. The synthesis was carried
through using polystyrene as solid-phase support and o-nitrobenzyl ether tether as linker. The target compound 2 was efficiently
obtained by iterative glycosylations, catalytic hydrogenation, acetylation, deacetylation, and photolysis.
Keywords: N, N’-Diacetyl-β-chitobiosyl N-glycooxazoline, synthesis, glycosylation, catalytic hydrogenation, photolysis
