addition, the relative rate ratio, kR/kS, of a kineticresolution during the Ru-catalyzed hydrogenation was found to be in a range 8–17, varying rather randomly as the alkyl group in 1 altered. The intercorrelation between the diastereoselectivity by virtue of the substrate-control and the kinetic discrimination of (±)-1 arising from the chiral catalyst-control was discussed in one particular case.
使用多种含有二膦和手性[Ru(OAc)2(S)-BIHAP]的Rh(I)阳离子络合物,将一系列外消旋甲基α-[α-(甲氧基羰基氨基)烷基]丙烯酸酯(1a-e)氢化( BINAP = 2,2'-双(二苯基膦基)-1,1'-二萘基)作为催化剂前体,优先提供苏式异构体(2a-d),其非对映异构体选择性主要取决于1中的烷基。此外,发现Ru催化加氢过程中动力学拆分的相对速率比k R / k S在8-17范围内,随着烷基在1中的变化而随机变化。改变了。在一种特定情况下,讨论了通过底物控制的非对映选择性与由手性催化剂控制引起的(±)-1动力学区分之间的相互关系。

The reaction of organozinc reagents with unactivated imines is accelerated when performed in the presence of a photocatalyst under blue light irradiation. Coordination between Lewis acidic zinc iodide and the imine is a key factor responsible for the reaction efficiency. The method can be carried out using alkyliodides under Barbier conditions.
