PROCESS FOR THE SYNTHESIS OF 3', 4'-DIDEOXYKANAMYCIN B

摘要

TITLE OF INVENTION: New process for the synthesis of 3',4'dideoxykanamycin B. A useful antibiotic, 3',4'-dideoxykanamycin B can be prepared in shortened steps and in an improved overall yield by a new process starting form kanamycin B via new intermediate derivatives of kanamycin B in which all the amino groups and possibly the 2"-hydroxyl group are protected with sulfonyl-type protecting groups selected from lower alkyl-, aryl- and aralkyl-sulfonyl groups.
