N-Substituted (3S,4S)- and (3R,4R)-pyrrolidine-3,4-diols 9 and 10, respectively, were derived from (+)-L- and (−)-D-tartaric acid, respectively. Compounds 9k, 9l, and 9m with the N-substituents, BnNH(CH2)2, 4-PhC6H4CH2NH(CH2)2 and 4-ClC6H4CH2NH(CH2)2, respectively, showed modest inhibitory activities toward α-D-amyloglucosidases from Aspergillus niger and from Rhizopus mold (Table 1). Unexpectedly
N-取代的(3 S,4 S)-和(3 R,4 R)-吡咯烷-3,4-二醇9和10分别来自(+)-L-和(-)-D-酒石酸酸。化合物9k中,9升和9米与Ñ -取代基,BnNH(CH 2)2,4-PHC 6 ħ 4 CH 2 NH(CH 2)2和4-CLC 6 ħ 4 CH 2 NH(CH 2)2分别显示了来自黑曲霉和根霉的α -D-淀粉葡糖苷酶的适度抑制活性(表1)。出乎意料的是,几种(3 R,4 R)-吡咯烷-3,4-二醇10显示出对来自杏仁和来自杰克豆的α -D-甘露糖苷酶的抑制活性(表3)。Ñ 3'-取代由NH 2(CH 2)2基团,即,10克,导致最高的效力。
