The products of dehydration of pentitols in aqueous sulfuric acid have been studied by g.l.c.-m.s.Four isomeric 1,4-anhydropentitols were formed from D-arabinitol, but only two from xylitol and ribitol.The number of products could only be explained by assuming inversion of configuration at C-2 or C-4 during 1,4- or 2,5-cyclisation reactions.No product which involved inversion of configuration at C-3 was observed.Various mechanisms of isomerisation are considered.
