This invention provides a method for enantioselective synthesis of cis-imidazolines and related structures through chiral resolution. A chiral acid is used to separate enantiomeric precursors of the cis-imidazolines from a racemic mixture by selective crystallization. Both enantiomers can be cyclized into the desired cis-imidazoline by complementary pathways. Compounds can be synthesized according to the invention with an enantiomeric excess as high as 99%. Cis-imidazolines such as Nutlin-3a prepared according to this invention may be used for treating cancer, killing senescent cells, or treating senescence-associated conditions.
这项发明提供了一种通过手性分辨法合成顺式咪唑啉和相关结构的方法。使用手性酸将顺式咪唑啉的对映体前体从混合物中分离出来,通过选择性结晶进行分离。两种对映体可以通过互补途径环化成所需的顺式咪唑啉。根据该发明合成的化合物的对映体过量可以高达99%。根据这项发明制备的Nutlin-3a等顺式咪唑啉可用于治疗癌症、杀死衰老细胞或治疗与衰老相关的疾病。
