A library of forty modified aminoglycosides was prepared in which the configuration and regiochemistry of two or three rings was widely varied. The library was based around three core ring systems: the 2-deoxystreptamine ring system found in the natural products, and both enantiomers of (1R*,2R*,4R*,5R*)-2,5-diamino-cyclohexane-1,4-diol and (1R*,3R*,4R*,6R*)-4,6-diaminocyclohexane-1,3-diol. In each
制备了四十个修饰的氨基糖苷文库,其中两个或三个环的构型和区域化学变化很大。该文库基于三个核心环系统:天然产物中存在的2-脱氧链胺胺环系统,以及(1R *,2R *,4R *,5R *)-2,5-二氨基-环己烷-1, 4-二醇和(1R *,3R *,4R *,6R *)-4,6-二氨基环己烷-1,3-二醇。在每种情况下,通过一个或两个糖环的糖基化修饰核心。糖取代基的绝对构型(d或l),端基异构中心(α或β)以及胺的区域化学排列均发生了变化。
