    摘要: There are provided new compounds, 3',4'-anhydro-4'-epi derivatives of kanamycin A of the formula: ##STR1## wherein R represents an alkyl, aralkyl or aryl group and Y represents an alkylidene, aralkylidene, cycloalkylidene or tetrahydropyranylidene group which are useful as an intermediate for the synthesis of 3',4'-dideoxykanamycin A and 4'-deoxykanamycin A from kanamycin A. The compounds of formula (I) can be prepared by treating the corresponding 4'-O-sulfonyl derivative with an alkali metal alcoholate in a lower alkanol under an alkaline condition.
