A simple procedure, which consists of direct heating of pyridinium chloride and the starting material, is described for the dehydration of alditols. Anhydroalditols, of great interest for various applications, are thus obtained, and the selectivity of the reaction is discussed. Some selective protections for further uses of these products are studied.

Various allyl ethers of 1,4-anhydro-D-sorbitol and pentaerythritol were synthesised as starting materials for self-metathesis reactions. Thus, dimeric compounds having six free hydroxy groups became accessible and should be used as potential analogues of dipentaerythritol for alkyd resin formation.
