The solid-phase synthesis of di-N-acetyl-β-chitobiosyl NAG (N-acetyl D-glucosamine)-thiazoline 3 was reported. After the 6-O-benzyl NAG-thiazoline 9, NHCbz trichloroacetimidate donors 14, and 21 were synthesized, and solid-phase synthesis was performed using the Wang resin as support. The target di-N-acetyl-β-chitobiosyl NAGthiazoline 3 was obtained by iterative glycosylation reactions, catalytic hydrogenation, acetylation, and deacetylation, respectively.
