                                    A new and convenient synthesis of 2-O-benzyl-3,4:5,6-di-O-isopropylidene-D-glucitol has been accomplished and has been generalized with the syntheses of differently protected D-glucitols at C-2 position. In the course of our new route to the differently protected D-glucitols at C-2 position, a new D-gluco configured building block, 1-morpholino-(3,4:5,6-di-O-isopropylidene)-D-gluconamide has been achieved.
