Cyclizations carba-sugar synthesis

Cyclization of 148 with l,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and a subsequent elimination reaction with acetic anhydride and pyridine furnished compound 149. °- Compound 149 was found to be an important key compound for the following synthesis of carba-sugars of the a-L-altro, fi-D-gluco, P-h-allo, and a-D manno modifications. [Pg.45]
