    • One aspect of the present invention relates to quinine-based and quinidine-based catalysts. In certain embodiments, the quinine-based and quinidine-based catalysts contain a hydroxy group at the 6′ position. In certain embodiments, the quinine-based and quinidine-based catalysts contain an O-aryl group or an O-aroyl group at the C9 position. In certain embodiments, the quinine-based and quinidine-based catalysts contain an optionally substituted O-diazene group or an optionally substituted O-benzoyl group at the C9 position. In certain embodiments, the quinine-based and quinidine-based catalysts contain a thiourea at the C9 position. In certain embodiments, the quinine-based and quinidine-based catalysts contain an NH(═S)NH-aryl group at the C9 position. Another aspect of the present invention relates to a method of preparing a chiral, non-racemic compound from a prochiral electron-deficient alkene or prochiral imine, comprising the step of: reacting a prochiral alkene or imine with a nucleophile in the presence of a catalyst; thereby producing a chiral, non-racemic compound; wherein said catalyst is a derivatized quinine or quinidine. In certain embodiments, the nucleophile is a malonate or β-ketoester. In certain embodiments the nucleophile is an alkyl or aryl or aralkyl 2-cyano-2-alkylacetate. In certain embodiments the nucleophile is an alkyl or aryl or aralkyl 2-cyano-2-alkylacetate.Another aspect of the present invention relates to a method of kinetic resolution, comprising the step of: reacting a racemic aldehyde or racemic ketone with a nucleophile in the presence of a derivatized quinine or quinidine, thereby producing a non-racemic, chiral compound. In certain embodiments, the kinetic resolution is dynamic.
    • 本发明的一个方面涉及基于奎宁和奎尼丁的催化剂。 在某些实施方案中,基于奎宁和奎尼丁的催化剂在6'位置含有羟基。 在某些实施方案中,基于奎宁和奎尼丁的催化剂在C 9位含有O-芳基或O-芳酰基。 在某些实施方案中,基于奎宁和奎尼丁的催化剂在C 9位含有任选取代的O-二氮烯基或任选取代的O-苯甲酰基。 在某些实施方案中,基于奎宁和奎尼丁的催化剂在C 9位含有硫脲。 在某些实施方案中,基于奎宁和奎尼丁的催化剂在C 9位含有NH(-S)NH-芳基。 本发明的另一方面涉及从前手性电子缺乏烯烃或前手性亚胺制备手性非外消旋化合物的方法,其包括以下步骤:在催化剂存在下使前手性烯烃或亚胺与亲核试剂反应 ; 从而产生手性,非外消旋化合物; 其中所述催化剂是衍生的奎宁或奎尼丁。 在某些实施方案中,亲核试剂是丙二酸酯或β-酮酯。 在某些实施方案中,亲核试剂是烷基或芳基或2-氰基-2-烷基乙酸烷基酯。 在某些实施方案中,亲核试剂是烷基或芳基或2-氰基-2-烷基乙酸烷基酯。 本发明的另一方面涉及一种动力学拆分方法,其包括以下步骤:在衍生化的奎宁或奎尼丁存在下,使外消旋醛或外消旋酮与亲核试剂反应,从而产生非外消旋的手性化合物。 在某些实施方案中,动力学分辨率是动态的。
