Starting from a common man-made chiral sugar building block, five out of eight L-aldohexoses have been synthesized in a diastereocontrolled manner to complete an integrated synthesis of the eight possible aldohexoses; the remaining three L-hexoses were synthesized from the same building block. Thus,

The intramolecular ene reaction of the 1,6-diene on a bicyclo[3.2.1]octane framework proceeds in a highly diastereoselective manner to form a trisubstituted pyrrolidine on the pyran ring in excellent yield. Its stereochemistry has been determined unambiguously by converting it into the known compoun
