Abstract

The TsOH catalized-LiBr assisted transacetalization from dimethoxymethane applied tomeso-erythritol1 and threitol5 allows the selective synthesis either of (4, 4, 0)-oxabicyclic compounds2 and6 or of 1, 3-diols3 and7. The relative configuration of the central carbon atoms proved to be critical to the reactivity of each tetraol, and is a key-factor for the determination both of the number and the structure of the expected products from this ...
