由二磷杂铑催化剂催化的各种甲基和叔丁基(Z)-2-(酰基氨基)-3-(杂芳基)丙烯酸酯的均相不对称氢化反应(见1a-f和2a-d,f,g,分别)对合成对映体纯的3-呋喃基,3-噻吩基和3-吡咯基丙氨酸进行了研究(参见3a–f和4a–d,g;方案1)。使用磷酸甘氨酸酯法(方案1)以高收率制备了前体(Z)-α-氨基-α,β-二氢化酯1a-f和2a-d,f,g。异构纯(Z)-α-氨基-α,β-二氢化酯需要获得不对称氢化中最高的对映体过量(ee's),而叔丁基酯策略从获得纯净的(Z)-α-氨基-α,β-二氢氢化酯,在氢化反应中获得较高的ee值。最后,与甲基酯系列相反,叔丁基酯4a-d,g的脱保护很容易使用CF 3 CO 2 H进行,没有任何消旋作用。

Compounds having the formula (I) pharmaceutical compositions containing them and their methods of use for the treatment of neurological disorders related to amyloid ß protein production and neurological disorders such as Alzheimer's disease.. These compounds inhibit γ secretase and thereby inhibit the production of amyloid ß protein, thereby acting to prevent the formation of neurological deposits of amyloid protein.
Compounds having the formula (1) pharmaceutical compositions containing them and their methods of use for the treatment of neurological disorders related to amyloid B protein production and neurological disorders such as Alzheimer's disease. These compounds inhibit γ secretase and thereby inhibit the production of amyloid β protein, thereby acting to prevent the formation of neurological deposits of amyloid protein.
Compounds having the formula (I) pharmaceutical compositions containing them and their methods of use for the treatment of neurological disorders related to amyloid β protein production and neurological disorders such as Alzheimer's disease. These compounds inhibit γ secretase and thereby inhibit the production of amyloid β protein, thereby acting to prevent the formation of neurological deposits of amyloid protein.
The invention provides a new method for treating disorders associated with activation of the Notch signal transduction pathway comprising administering an effective amount of a compound of Formula (I), in free form or in a pharmaceutically acceptable salt form or in the form of a pharmaceutically acceptable solvate of the compound or the salt, to a human or animal patient in need thereof.
