制備方法
方法一
3’,4’-二脫氧卡那霉素B和等當(dāng)量的叔丁氧羰基疊氮化物,在水、吡啶和三乙胺(10:10:1)的混合溶液中,在室溫下反應(yīng)18h。然后用Amberlite CG50(NH4+)柱層析,得6’-N-叔丁氧羰基-3’,4’-二脫氧卡那霉素B,收率49%,熔點(diǎn)136~140℃(分解),[α] {D}^26+112°(C=1.0,水)。同時(shí)回收36%未反應(yīng)的3’,4’-二脫氧卡那霉素B。6’-N-叔丁氧羰基-3’,4’-二脫氧卡那霉素B(1.1g,2.0mmo1)和叔丁氧羰基疊氮化物(320mg,2.2mmo1)在和上述相同的條件下反應(yīng),得到1.41g黃色粉末。不用提純,溶于20ml水和10ml二甲氧基乙烷,用(S)-4-叔丁氧羰基氨基-2-羥基丁酸(N-羥基丁二酰亞胺)酯(696mg,2.2mmo1)在10ml二甲氧基乙烷中的溶液,在室溫下酰化20h。和10ml 90%三氟乙酸在室溫下反應(yīng)40min,移去叔丁氧羰基。反應(yīng)液濃縮至于,用Amberlite CG50(NH4+)柱層析,用水和0.5mol/L氨水洗脫后,再用0.75mol/L氨水將產(chǎn)物洗脫。得162mg二碳酸阿貝卡星,收率12%,熔點(diǎn)178℃(分解),[α]{D}^24+87°(C=0.77,水)。
