An efficient and practical strategy for the synthesis of unknown azetidine iminosugars (2S,3R,4S)-2-((R)-1,2-dihydroxyethyl)-3-hydroxy-4-(hydroxymethyl)azetidine 2, (2S,3r,4R)-3-hydroxy-2,4-bis(hydroxymethyl)azetidine 3 and (2S,3R,4S)-3-hydroxy-4-(hydroxymethyl)-N-methylazetidine-2-carboxylic acid 4, starting from the d-glucose has been reported. The methodology involves preparation of the 3-amino
合成未知氮杂环丁烷亚氨基糖(2 S,3 R,4 S)-2-((R)-1,2-二羟乙基)-3-羟基-4-(羟甲基)氮杂环丁烷2,( 2 S,3 r,4 R)-3-羟基-2,4-双(羟甲基)氮杂环丁烷3和(2 S,3 R,4 S)-3-羟基-4-(羟甲基)-N-甲基氮杂环丁烷-已经报道了从d-葡萄糖开始的2-羧酸4。该方法学涉及3-氨基-N-苄氧基羰基-3-脱氧-6-的制备。ø -叔-butyldimethylsillyl -1,2- ö异亚丙基α - d -glucofuranose 9,将其转化成C-5- OMs的衍生物11。C-5- OMs基团的分子内亲核置换和原位产生的3-氨基官能团为所需的关键氮杂环丁烷环骨架10提供了额外的羟甲基基团。除去1,2-丙酮化物保护,然后还原和氢解,得到氮杂环丁烷亚氨基糖2。或者,除去1,2-丙酮化物基团并切断C 1-异头碳,得到C 2-醛,其经还原或氧化
