A divergent synthesis of cyclitolderivatives has been developed utilizing an N‐heterocyclic carbene‐catalyzed benzoin‐type cyclization of C2‐symmetrical dialdoses. The resulting inososes are versatile intermediates, which are readily converted into not only inositols but also amino‐, deoxy‐, O‐methyl‐ and C‐methyl‐inositols.
