of asymmetric cyclization reactions of 1,6-enynes have been established, simple asymmetric reductive cyclization remains underdeveloped. In this study, the enantioselective reductive cyclization of alkynyl-tethered cyclohexadienones (1,6-enynes) has been developed via a chiral pincer rhodium catalyst, affording cis-hydrobenzofurans and cis-hydroindoles with high enantioselectivities (90–99% ee). Furthermore
尽管已经建立了各种类型的1,6-烯炔的不对称环化反应,但简单的不对称还原环化反应仍然不发达。在这项研究中,通过手性钳铑催化剂开发了炔基束缚的环己二酮(1,6-烯炔)的对映选择性还原环化,得到具有高对映选择性(90-99% ee)的顺式氢苯并呋喃和顺式氢吲哚。此外,还介绍了针对 SARS-CoV-2 3CL pro 的几种合成应用和初步抑制活性研究。
