Hydrogenation of a series of cyclic beta-(acylamino)acrylates with tetrasubstituted olefins has been accomplished successfully with the use of Ru catalysts with chiral biaryl ligands such as C3-TunaPhos, and up to over 99% ee's have been achieved. This methodology provides an efficient catalytic method for the synthesis of both cis and trans chiral cyclic beta-amino acid derivatives.
使用具有手性联芳基配体(如 C3-TunaPhos)的 Ru 催化剂成功地完成了一系列环状 β-(酰氨基)丙烯酸酯与四取代烯烃的氢化,并且已实现高达 99% 以上的 ee。该方法为顺式和反式手性环状β-氨基酸衍生物的合成提供了一种有效的催化方法。
