CHIRAL OXETANES FROM SUGAR LACTONES - SYNTHESIS OF DERIVATIVES OF 3,5-ANHYDRO-1,2-O-ISOPROPYLIDENE-ALPHA-D-GLUCURONIC ACID AND OF 3,5-ANHYDRO-1,2-O-ISOPROPYLIDENE-BETA-L-IDURONIC ACID
Ring contraction reactions of triflates of α-hydroxy-γ-lactones provide an approach to the synthesis of chiral polyfunctionalised oxetanes from sugars. Treatment of 1,2-0-isopropylidene-5-0-trifluoromethanesulphonyl-α-D-glucuronolactone with benzylamine or with potassium carbonate in methanol gave r...
