A new convenient synthesis of (2S,3R)-2-O-benzyl-3,4-O-isopropylidene-d-erythritol has been achieved starting from extremely cheap and commercially available d-(+)-glucono-δ-lactone. It involves two carbon excisions using ozonolysis. The inbuilt stereochemistry ensures the enantiopurity of the target compound.
