An asymmetric hydrogenation of aroylacrylic acids catalyzed by RuPHOX-Ru catalyst has been developed, affording the corresponding chiral γ-lactones in high yields and with up to 93% ee. The methodology has the advantage of utilizing easily accessible substrates and has therefore expand the scope of the resulting chiral γ-lactones. Furthermore, high catalytic efficiency was achieved in that the reduction
已经开发了通过RuPHOX-Ru催化剂催化的芳酰基丙烯酸的不对称氢化,以高收率和高达93%的ee提供了相应的手性γ-内酯。该方法具有利用容易获得的底物的优点,因此扩大了所得手性γ-内酯的范围。此外,由于一步实现了C C和C O双键的还原,因此实现了高催化效率。目前的工作为广泛的手性γ-内酯的合成提供了另一种方便的途径。
