title: Enantioselective synthesis of 2,6-dideoxy carbasugars based on a desymmetrizing hydroformylation-carbonyl ene cyclization process.
abstract: A practical one-pot process involving a desymmetrizing hydroformylation with the aid of a chiral catalyst-directing group (CDG*), followed by a carbonyl ene cyclization provides a straightforward access to both enantiomers of the resulting cyclohexanediol; further divergent, highly selective and protecting group-free transformations furnish the carbocyclic analogues of four important 2,6-dideoxysugars.
