The cyclopentenylacetaldehyde (1) required for the synthesis of prostacyclin (prostaglandin I2) and other prostanoids is now readily available from the preparation and rearrangement of 7-substituted norbornadienes.

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.

An efficient route to optically pure prostaglandin-J2 compounds has been discovered: ent-PGJ2 is shown to display anti-viral activity against Sendai virus with a similar potency to the natural enantiomer.
