here a range of new sucrose derivatives obtained from '3-ketosucrose' in aqueous medium with few reaction steps. As an intermediate, 3-amino-3-deoxy-alpha-D-allopyranosyl beta-D-fructofuranoside (1) was obtained via the classical route of reductive amination with much improved yield and high stereoselectivity. Building blocks for polymerization were synthesized by introduction of acrylic-type side
我们在这里报告了从“ 3-酮蔗糖”在水性介质中以很少的反应步骤获得的一系列新的蔗糖衍生物。作为中间体,通过经典的还原胺化途径获得了3-氨基-3-脱氧-α-D-戊吡喃糖基β-D-果糖呋喃糖苷(1),具有大大提高的收率和高的立体选择性。通过引入丙烯酸类侧链(例如,与甲基丙烯酸酐)来合成用于聚合的结构单元。合成了相应的聚合物。通过具有活化和保护氨基酸的常规肽合成获得氨基酰基和肽缀合物。脱保护得到具有非常规取代模式的新糖衍生物,即3-(氨基酰基氨基)同种糖。已经合成了异蔗糖的单肽和二肽缀合物。
