with green reagents and solvent dimethyl carbonate (DMC) is reported. Dehydration of D-
sorbitol via DMC in the presence of catalytic amounts of base is an efficient and viable
process for the preparation of the industrially relevant anhydro sugar isosorbide. This
procedure is “chlorine-free”, one-pot, environmental friendly and high yielding. The reactivity
of isosorbide with DMC is equally interesting as it can lead to the formation of …
