A stereoselective synthesis of the apoptolidin disaccharide is reported. The key chemistry features a new transformation utilizing a highly selective tetramethylalkoxyalanate[v]-directed syn-methylation of a vinylogous ester, isolation of a hydrate of a 2-keto sugar, an eco-friendly radical cleavage of a bromomethyl group, and an efficient preparation of a fluorodisaccharide via the use of XtalFluor-E
报道了凋亡素二糖的立体选择性合成。关键化学的特征是利用乙烯基酯的高选择性四甲基烷氧基丙二酸酯[v]指导的合成甲基化,分离2-酮糖的水合物,对溴甲基进行生态友好的自由基裂解以及高效的新转化通过使用XtalFluor-E制备氟二糖。
