The first interrupted asymmetric hydroaminomethylation reaction was developed. The challenging trans-1,2-disubstituted olefins were employed as substrates, and a series of valuable chiral pyrrolidinones and pyrrolidines were obtained in high yields with high regioselectivities and excellent enantioselectivities. Several synthetic transformations were conducted, demonstrating the high synthetic utility
开发了第一个间断的不对称氢氨甲基化反应。具有挑战性的反式-1,2-二取代烯烃被用作底物,并以高产率、高区域选择性和优异的对映选择性获得了一系列有价值的手性吡咯烷酮和吡咯烷。进行了几次合成转化,证明了我们方法的高合成效用。还开发了合成 vernakalant 和 Enablex 的创造性路线。
