The solid-phase synthesis of di-N-acetyl-β-chitobiosyl allosamizoline 2 was reported. After the 6-O-benzyl allosamizoline 16, NHCbz trichloroacetimidate donors 7, and 14 were synthesized; solid-phase synthesis was performed using the Wang resin as support. The target di-N-acetyl-β-chitobiosyl allosamizoline 2 was obtained by iterative glycosylation reactions, catalytic hydrogenation, acetylation, and deacetylation, respectively.
