The synthesis of the first enantiopure planar-chiral thiourea catalysts is herewith described. New catalysts 1-3 were applied in asymmetric transformations, such as the Friedel-Crafts alkylation of indole, as well as in the transfer hydrogenation of nitroolefins. Bifunctional catalysts 2 and 3 exhibit enhanced activity in the investigated reactions, demonstrating their potential for organic synthesis
在此描述了第一种对映体纯平面手性硫脲催化剂的合成。新催化剂1-3应用于不对称转化,如吲哚的Friedel-Crafts烷基化,以及硝基烯烃的转移加氢。双功能催化剂 2 和 3 在所研究的反应中表现出增强的活性,证明了它们在有机合成方面的潜力。
