- SYNTHESIS OF SOME L-IDOSE DERIVATIVES
-
The synthesis of 3-O-benzyl and 3-O-mesyl-1,2-O-isopropylidene-β-L-idofuranose has been effected on the basis of the intramolecular nucleophilic exchange of a mesyloxy group at C5 in derivatives of 1,2-O-isopropylidene-α-D-glucofuranose.It has

-
Simple preparative routes to 1,2-O-isopropylidene- and 1,2:5,6-di-O-isopropylideneβ-L-idofuranoses are described.The 1,2:5,6-diacetal is the kinetic product of the reaction of 1,2-O-isopropylidene-β-L-idofuranose with acetone and 2,2-dimethoxypropane in the presence of toluene-p-sulphonic acid but, during longer reaction times, isomerisation to 1,2:3,5-di-O-siopropylidene-β-L-idofuranose occurs, resulting in a approximately equal mixture of the two diacetals.
