Abstract The α- l -fucopyranosyl- myo -inositol isolated from human urine has been proved to be the 1 d -4- O - myo -inositol derivative by unambiguous syntheses of this substance and of the diastereomeric 1 l -4- O - myo -inositol derivative. The chiral penta- O -benzoyl- myo -inositols used in the glycosidations, by the imidate method, were prepared from 1 d - and 1 l -4- O -benzyl- myo -inositol
