A method for the preparation of cyclopentenones of the general formula (VIII): ##STR1## wherein n is 5-7, has been developed which proceeds via the acid catalyzed deprotection and rearrangement of novel substituted-.alpha.-hydroxymethylfurans of general formula (VII): ##STR2## wherein R is a hydroxyl protecting group, R.sub.1 and R.sub.2 are methyl or ethyl or together form --(CH.sub.2).sub.3 -- and n is as above described. Cyclopentenones of formula VIII are useful intermediates in prostaglandin analog synthesis.
