This invention refers to use of cymipristone type compounds of formula (I), salt or solvate thereof in preparation of medicament for treating AIDS. Cymipristone type compounds are a new type glucocorticoid receptor antagonist. Pharmacological test shows that cymipristone has anti-glucocorticoid activity and very strong affinity with glucocorticoid receptor. Test indicates that cymipristone is a glucocorticoid antagonist on receptor level and can block the function of glucocorticoid receptor. The inventor uses cymipristone to test the inhibition on the growth of AIDS virus in vitro and finds that cymipristone has significant growth inhibition action on AIDS pathogen HIV-1.

The special reactivity of N,N-dialkylaniline N-oxides allows practical and convenient access to electron-rich aryl halides. A complementary pair of reaction protocols allow for the selective para-bromination or ortho-chlorination of N,N-dialkylanilines in up to 69% isolated yield. The generation of a diverse array of halogenated anilines is made possible by a temporary oxidation level increase of N
N,N-二烷基苯胺N-氧化物的特殊反应性使得可以方便实用地获得富含电子的芳基卤化物。一对互补的反应协议允许用于选择性对-bromination或邻位的-chlorination N,N- -dialkylanilines在高达69%的分离收率。通过将N,N-二烷基苯胺暂时氧化为相应的N,N-二烷基苯胺N-氧化物并去除生成的弱N – O ,可以生成各种卤化苯胺 通过在低温下用亚硫酰溴或亚硫酰氯处理可实现键合。
