We report herein the synthesis of various derivatives of isomannide and isosorbide. Alkylation on N-(diphenylmethylene)glycine tert-butyl ester show the new catalysts to be effective phase-transfer catalysts with moderately good enantioselectivity. The ef

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.
