The synthesis of the carbasugar of β-galactosamine-(1,4)-3-O-methyl-D-chiro-inositol (INS-2), a potential tool for studying glucose metabolism, is described. The synthetic strategy, entails an oxocarbenium ion cyclization on a chiro-inositol derived, thioacetal-enol ether to give a carbocyclic enol ether, which is elaborated to the 2-amino-2-deoxy carbasugar framework via a 2-oximo derivative.
描述了β-半乳糖胺-(1,4)-3-O-甲基-D-手性肌醇(INS-2)的碳环糖的合成,这是一种研究葡萄糖代谢的潜在工具。该合成策略涉及在手性肌醇衍生的硫缩醛-烯醇醚上进行氧杂碳正离子环化,得到碳环烯醇醚,然后通过 2-肟衍生物将其进一步构建为 2-氨基-2-脱氧碳环糖骨架。
