Abstract

NEW MATERIAL:Maltosan derivatives of formula V (Ac is acetyl; R is H, acetyl).
EXAMPLE: 3'-Acetylamino-3'-deoxy-maltosan.
USE: Synthetic intermediate of aminoglycoside antibiotics: they are also useful as antimicrobial. The present invention is characterized by using, as the starting material, maltosan readily derived from maltose available in a large amount.
PREPARATION: Maltosan, which is derived from maltose through several procedures, is oxidized with periodic acid to form a compound of formula II. The product is made to react with nitromethane to convert to a compound of formula III, which is reduced to a compound of formula IV. The compound of formula IV is subsequently acetylated to a compound of formula V (R=Ac). When necessary, it is subjected to ester-interchange reaction in the presence of sodium methoxide to convert to a compound of formula V (R=H).
