The solid-phase synthesis of allosamidin was investigated. After two N-benzyloxycarbonyl (Cbz)-protected trichloroacetimidate donors were synthesized, the solid-phase synthesis was performed using polystyrene as support and an o-nitrobenzyl ether tether as linker. The target allosamidin was efficiently obtained by iterative glycosylation reactions, catalytic hydrogenation, acetylation, deacetylation
The solid-phase synthesis of allosamidin is described. After the NHCbz trichloroacetimidate donors were synthesized, solid-phase synthesis was performed using the Wang resin as support. The target allosamidin was obtained by iterative glycosylation reactions, catalytic hydrogenation, acetylation, and deacetylation, respectively.
