aminoheptenitols 5–8 (prepared in three steps from ) provided 1,2,6-trideoxy-2,6-imino-liodoheptitol derivatives 9–12, respectively, highly stereoselectively and in high yield. The “” epimer 9 was used in the synthesis of a precursor of an aza-C-disacharide and its reaction with triethyl phosphite was investigated.
NIS介导的氨基庚糖醇5-8的环化反应(从制备三个步骤开始)分别提供了1,2,6-丁氧基-2,6-亚氨基碘代庚糖醇衍生物9-12,具有高立体选择性和高收率。将“ ”差向异构体9用于合成氮杂-C-二糖苷的前体,并研究了其与亚磷酸三乙酯的反应。
