title: Synthesis of furo[2,3b]furans and furo[2,3b]pyrans via rhodium-catalyzed tandem hydroformylation/acetalization.
abstract: [reaction: see text] Rhodium-catalyzed tandem hydroformylation/acetalization of alpha,omega-alkenediols gives facile access to perhydrofuro[2,3b]furans and perhydrofuro[2,3b]pyrans in good yields. Similarly, benzoannelated tetrahydrofuro[2,3b]furans are obtained by hydroformylation of o-hydroxy cinnamyl alcohols.
