Linearization of carbohydrate derived polycyclic frameworks

We report easy access to carbohydrate derived diverse tricyclic skeletons which could be beneficial for exploring polyfunctionalized chiral alicycles. The key reaction to assemble a sugar fused tricyclic core is intermolecular tandem esterification and 1,3-dipolar cycloaddition. The framework was elaborated using amide forming reactions, opening of isoxazolidine rings followed by N and O-acylations. The sequences provide distinct, spatially separated and encoded chemical entities that may pave the way to investigate cell functions.

SYNTHESIS OF A 4-AMINO-4-DEOXY-D-GALACTURONIC ACID DERIVATIVE

The hitherto unknown methyl (methyl 4-amino-2,3-di-O-benzyl-4-deoxy-α-D-galactopyranosid)uronate (11) has been prepared in six steps from methyl 2,3-di-O-benzyl-6-O-(4-methoxybenzyl)-α-D-glucopyranoside (1).Treatment of 1 with methanesulfonyl chloride and
