system are reported. This process provides a highly efficient method for the synthesis of optically active tetrahydroquinolines, with one or two chiral centres at different positions as well as highly divergent functional groups, in good to excellent yields and with high regio-, diastereo- and enantioselectivities. A preliminary study on the effect of stereochemistry on biological activity suggests a potential
报道了由金(I)/布朗斯台德酸合作体系催化的氨基苯甲醛或氨基苯酮与炔烃的一锅顺序不对称反应。该方法提供了一种高效的合成光学活性四氢喹啉的方法,该方法具有一个或两个在不同位置的手性中心以及高度分散的官能团,收率高至优异,并且具有高的区域,非对映和对映选择性。对立体化学对生物活性影响的初步研究表明,这些光学活性的四氢喹啉在药物发现过程中具有潜在的应用前景。
