Derivatives of 2-C-branched-chain erythrono-1 ,Clactones of the type 1 have been synthesized under reductive conditions using DIBAL from the oxetane 2, which is easily accessible from diethyl mesoxalate (4) and 2,2-diisopropyl-1,3-dioxole (3) in high yield by means of a catalytic cycloaddition. Simi
