The cycloaddition of α,β-epoxyaldehydes or ketones (2) with the ketene acetal MeHC=C(OMe)2 (1) gives epoxyoxetanes (3) in high yields.Without isolation they can be transformed into 4-hydroxy-5-(1-hydroxyalkyl)-γ-butyrolactones (6) via the epoxy esters 4 and trihydroxy esters (5).The lactones 6 appear to be valuable precursors for the synthesis of 5-(1-hydroxyalkyl)-3-methyl-2-5H-furanones (7) and 3-methyl-5-ylidene-2-5H-furanones (8)
