Syntheses of 7-substituted norbornadienes from 7-t-butoxy- and 7-halogeno-norbornadienes are described. Rearrangement of the products in the presence of peracetic acid gives bicyclic aldehydes (2) in equilibrium with enol ethers (3) which are hydrolysed to hydroxycyclopentenylacetaldehydes (4), and converted into key intermediates for the synthesis of prostaglandins and their analogues. Syntheses of
