A one pot stereoselectivesynthesis of cis or trans 2,5-disubstituted tetrahydrofurans 3–8 can be achieved in high yields via electrophilic cyclisation of the corresponding cis or trans α or γ-allyl-β-hydroxyesters mediated by metachloroperoxybenzoic acid. The tetrahydrofurans 5 or 6 may be converted into (±) methylnonactate by procedures described earlier. The role of methoxycarbonyl group during
