glucuronolactone are excellent chirons for the synthesis of the 10 stereoisomeric 2,5-dideoxy-2,5-iminohexitols by formation of the pyrrolidine ring by nitrogen substitution at C2 and C5, with either retention or inversion of configuration; the stereochemistry at C3 may be adjusted during the synthesis to give seven stereoisomers from each enantiomer. A definitive side-by-side comparison of the glycosidase
葡糖醛酸内酯的对映体是用于合成10个立体异构体2,5-二脱氧-2,5-亚氨基己糖醇的优秀的Chirons,通过在C2和C5处进行氮取代形成吡咯烷环,而保留或反转构型。在合成过程中,可以调节C3处的立体化学,以从每种对映异构体中产生7种立体异构体。对一组13种糖苷酶的糖苷酶抑制作用的确定性并排比较显示,这10种立体异构体中有8种对至少一种糖苷酶具有明显的抑制作用。
