Abstract

1,5-Anhydro-D-fructose (AF) is a valuable chiral building block[1,2] which is available by degradation from starch by a-1,4-glucan lyase[2] and which now also can be produced by efficient synthetic proedures.[3] AF has three different functional hydroxyl groups, a pro-chiral center and a permanent pyran ring thus making selective manipulations possible. In the present work methods for stereoselective amino functionalisation at C-2 has been developed to give 2-amino-2-deoxy-1,5-anhydroalditols with manno- and gluco-configuration, respectively. The 2-acetamido-2-deoxy-1,5-anhydroglucitol has been shown to cause feeding suppression. An efficient synthesis of the important glycosidase inhibitor deoxymannojirimycin (DMJ) from AF has been achieved. Acetylation of AF gives the unsaturated ketone[2,4] which was used for preparation of the natural product Clavulazine as well as the valuable antioxidant Ascopyrone P. [1] S. M. Andersen, I.
