An efficient intramolecular [2+2] photocycloaddition of alkyl hex-2-enopyranosid-4-uloses allows the construction of two new cyclic systems annelated to the pyranoside moiety with stereocontrol of 3 or 4 carbogenic centers. The regioselective ring cleavage of the cycloadducts affording new bicyclic pyranoid compounds is described.
