Presented here are several examples which demonsrrate that ether substituenul a-oc fl-to an epoxide ring can be tolerated iu the ring-opening naction with B\_keto ester dianicms. Subsequent acidpromoted cyclisariou of the y-hydroxy &ketoesters then leads to synthetically useful tetrahydrofurans, as
