A practical one-pot process involving a desymmetrizinghydroformylation with the aid of a chiral catalyst-directinggroup (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
