Intramolecular aldol condensation applied to D-glucose-derived δ-ketoaldehydes: Access to enantiomerically pure six-membered carbocycles

An enantiomerically pure δ-ketoaldehyde 10, efficiently prepared from D-glucose, was subjected to an intramolecular aldol condensation. By using DBU as a base, the expecting aldol reaction took place smoothly giving the aldol 11 stereoselectively. Further
