A Straightforward Preparation of Both Enantiomerically Pure 2-O-Benzyl-erythro-Butanetetrols

Article abstract of DOI:10.1016/0957-4166(95)00194-T

A short and efficient synthesis of both enatiomerically pure 2-O-benzyl-erythro-butanetetrols 4 and ent-4 from the readily available D-erthronolactone 1 is presented.The synthesis proceeds in a highly efficient manner and is in both cases substrate controlled.
