Acid-induced electrocyclic ring-closure of (2Z)-4-tert-butyl-3-methyl-2,4,5,7-tetraene acetals 3 afforded a mixture of alkylidenecyclopentene dioxanes Z-4 and E-4. The lack of torquoselective effects on the electrocyclization suggested the transition stat

Inter- and intramolecular trapping experiments and density functional theory ab initio calculations for model systems are consistent with the acid-catalyzed rearrangement of 2-[(1Z)-hexa-1,3,4-trienyl]dioxolanes 1 to tetrahydroalkylidenecyclopenta-1,4-dio
