Two synthetic strategies employing organometallic addition to hemiacetalic sugars followed by selective nucleophilic displacement or conjugate addition of ammonia to conjugate aldonic esters as key steps, are used. The new compounds were assayed for their inhibitory activity towards 13 commercially available glycosidases. Compounds that share the absolute configuration at C(2,3,4,5) of L-fucopyranosides
立体选择性合成新的3,4-二羟基吡咯烷衍生物 D-甘露糖, D-核糖 和 L-岩藻糖被表达。两种合成策略是将有机金属添加到半缩醛糖中,然后进行选择性亲核取代或共轭添加氨使用共轭醛糖酸酯作为关键步骤。测定了新化合物对13种市售糖苷酶的抑制活性。在L-岩藻糖苷的C(2,3,4,5)处具有绝对构型并包含芳香族部分的化合物是有效的和选择性的nM范围内的α-L-岩藻糖苷酶抑制剂。
