A desymmetrization-based approach for the synthesis of piperidinyl acetic acid γ-secretase modulators has been developed. The synthetic sequence features the use of N-tert-butanesulfinyl imine reduction and a diastereoselective lactam formation to set up the chiral centers. The synthetic utility is demonstrated by the concise asymmetric synthesis of γ-secretase modulator GSM-1.
已经开发了一种基于去对称化的方法来合成哌啶基乙酸 γ-分泌酶调节剂。合成序列的特点是使用N-叔丁亚磺酰亚胺还原和非对映选择性内酰胺形成来建立手性中心。γ-分泌酶调节剂 GSM-1 的简明不对称合成证明了该合成效用。
