A novel class of squalene synthase inhibitors (J-104,118 and J-104,123) were synthesized efficiently. An amine intermediate 1 was synthesized using two distinct methods. First, the racemic amine 1 was synthesized diastereoselectively using a key reaction consisting of the stereo-controlled reduction of the ketone 7 by L-Selectride®. Second, the optically active amine 1 was synthesized efficiently and
有效合成了新型的角鲨烯合酶抑制剂(J-104,118和J-104,123)。使用两种不同的方法合成了胺中间体1。首先,外消旋胺1是通过关键反应非对映选择性合成的,该关键反应由L-Selectride®对酮7进行立体控制的还原反应组成。其次,使用Sharpless二羟基化作为关键反应,高效地和对映选择性地合成了光学活性胺1。从可商购的(R)-3-羟基丁酸甲酯开始开发了一种立体控制的合成J-104,123的方法。
