Process for the synthesis of 3{40 ,4{40 -dideoxykanamycin B and products

摘要

A useful antibiotic, 3',4'-dideoxykanamycin B can be prepared in shortened steps and in an improved overall yield by a new process starting from 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.
