The present invention relates chiral 1, 3-diarylimidazole salt carbene precursors, their methods of preparation, particularly transition metal complexes and their use in chemical synthesis. An air and moisture stable chiral 1, 3-diarylimidazole carbene precursor Cu (I) complex has been prepared and applied to highly regio- and enantioselective Markovnikov hydroboration of unactivated terminal alkenes to form chiral boronic esters. Moreover, these new chiral NHCs can be potentially applied in various metal-catalyzed asymmetric transformations.
本发明涉及手性 1,3-二咪唑盐碳烯前体及其制备方法,特别是过渡金属配合物及其在化学合成中的应用。本发明制备了一种空气和湿度稳定的手性 1,3-二咪唑碳烯前体 Cu (I) 复合物,并将其应用于未活化末端烯烃的高区域和对映选择性 Markovnikov 烃硼化反应,以形成手性硼酸酯。此外,这些新的手性 NHC 可用于各种金属催化的不对称转化。
