experimental part, p. 2260 - 2265 (2009/07/18)
A novel family of chiral imidazolium-based ionic liquids containing a chiral moiety and a free hydroxyl function has been designed and synthesized using isosorbide as a biorenewable substrate. These chiral ionic liquids were found to catalyze the aza Diels-Alder reaction to give good yields and moderate diastereoselectivities. Chiral ionic liquids are recycled while their efficiency is preserved.

A novel method for the synthesis of ethers of anhydrosugars, such as isosorbide, isomannide, and isoidide, is disclosed. The bisglycidyl ethers are useful as substitutes for bisphenol A in the manufacture of thermoset epoxy ethers. Anhydrosugar ethers are

Each of the two hydroxyl groups of isosorbide can be alkylated selectively, either by direct alkylation with benzyl chloride or allyl bromide according to the reaction conditions, or by a three-step procedure involving selective monoacetylation, alkylation with four different reagents, and finally deacetylation.Monobutyl and monomethyl derivatives from isosorbide are also described.
