Three diastereoisomers of 3-amino-4-hydroxy-2-(hydroxymethyl)pyrrolidine have been synthesised by a divergent route starting from trans-4-hydroxy-L-proline. Regio- and stereoselective introduction of the 3-amino and 4-hydroxyl functional groups was achieved using either a tethered aminohydroxylation reaction or by employing intra- and intermolecular epoxide-opening strategies. Preliminary biological data indicate that two of these novel amino pyrrolidines are moderate inhibitors of β-galactosidase.
以反式-4-羟基-L-脯氨酸为起点,通过不同的路线合成了 3-氨基-4-羟基-2-(羟甲基)吡咯烷的三种非对映异构体。通过系链氨基羟化反应或分子内和分子间环氧化物开环策略,实现了 3-氨基和 4-羟基官能团的区域和立体选择性引入。初步生物数据表明,这些新型氨基吡咯烷中的两种是β-半乳糖苷酶的温和抑制剂。
