<p>Novel amino polyol derivtives represented by (I), wherein R and R" each represent hydrogen, alkyl or aryl or, when taken together, R and R" represent alkylene, R1 represents lower alkyl, R2 represents hydrogen or acyl, and R3 represents lower alkyl, and a process for preparing them using (II) and (III), as starting materials. The amino polyol derivatives (I) are useful as intermediates for synthesizing amino sugars such as daunosamine, 3-epi-daunosamine, acosamine, ristosamine, etc. which constitutes the sugar moiety of daunomycin useful as oncostatic agent. </p> |
