Disclosed is a novel inosose compound represented by the general formula:
wherein X¹ and X² are both halogen; X¹ is hydrogen and X² is halogen; or X¹ is -SQ¹ and X² is -SQ² (each of Q¹ and Q² is lower alkyl or Q¹ and Q² may form lower alkylene), R¹ is a protective group for hydroxyl and Y is =O, =N-Z (Z is hydroxyl which may be protected) or
HA (A is hydrogen or an amine residue), particulaly to the compound wherein the symbol Y is oxygen.
The inosose compound is useful as intermediates for production of valiolamine and the N-substituted derivatives thereof, which have potent α-glucosidase inhibiting activities and are useful as preventives or therapeutics for symptoms of hyperglycemia and various diseases derived therefrom in human and animals, such as diabetes, obesity and hyperlipemia.
