Four aminocyclopentanols, as mimics of putative intermediates in the hydrolysis of α-D-galactosides, have been synthesized through a number of stereoselective transformations using the cis-fused cyclopentane-1,4-lactone (1R, 5S, 7R, 8R)-7,8-dihydroxy-2-oxabicyclo[3.3.0]oct-3-one 1 as a chiral building block. The compounds were tested towards various glycosidases but showed no anomer selectivity in the inhibition of α- and β-galactosidases.
以顺式融合的环戊烷-1,4-内酯(1R, 5S, 7R, 8R)-7,8-二羟基-2-氧杂双环[3.3.0]辛-3-酮 1 为手性结构单元,通过一系列立体选择性转化合成了四种氨基环戊醇,它们是δ-D-半乳糖苷水解过程中假定中间体的模拟物。这些化合物针对各种糖苷酶进行了测试,但在抑制δ-和²-半乳糖苷酶方面没有显示出同分异构体的选择性。
