The epoxy alcohol exo-6-hydroxy-exo-4-oxatetracyclo(6.2.1.0.2,703,5)-undec-9-ene (1a) was synthesized by photooxygenation of dicyclopentadiene in the presence of Ti(OiPr)4; vacuum flash pyrolysis (520 deg C) of 1a resulted in 3,4.epoxy-5-hydroxycyclopentene (2) as intermediate, wich at elevated temperature rearranged into the cis- and trans-2,4-pentadienoic acids (8).
