The divergent synthesis of some novel aminocyclopentitol analogues was concisely achieved from readily available d-galactose via the highly diastereoselective amination of carbocyclic polybenzyl ether using chlorosulfonyl isocyanate, diastereoselective dihydroxylation, and epoxidation as the key steps.
