Using D-serine as a chiral precursor, a polyhydroxylated pyrrolidine (1), its derivatives bearing carboxylate, phosphate and phosphonate groups (2–4) and an oxapyrrolizidine (5) were synthesized. The pyrrolidine ring was formed by intramolecular amino-mercuration. The bicyclic scaffold of oxapyrrolizidine was further constructed by an intramolecular attack of the carbamate group on the iodomethyl group. Compounds 1 and 5 were found to inhibit β-glucosidase and α-galactosidase, respectively, in a competitive manner, whereas compounds 2, 3 and 4 did not produce significant inhibition against glycosidases.
使用 D-丝氨酸作为手性前体,合成了多羟基化吡咯烷 (1)、其带有羧酸酯、磷酸酯和膦酸酯基团的衍生物 (2-4) 以及奥沙吡咯里西啶 (5)。通过分子内氨基汞化形成吡咯烷环。通过氨基甲酸酯基团对碘甲基的分子内攻击进一步构建了奥沙吡咯里西啶的双环支架。发现化合物1和5分别以竞争性方式抑制β-葡萄糖苷酶和α-半乳糖苷酶,而化合物2、3和4对糖苷酶没有产生显着的抑制作用。
