1,2-reductive dearomatization of quinolines and copper(II) acetate monohydrate/(R,R)-Ph-BPE/P(p-tolyl)3-catalyzed enantioselective hydroamination sequence was developed, affording diverse 4-amino-1,2,3,4-tetrahydroquinolines with high levels of enantioselectivity in either a stepwise or one-pot fashion. Pleasingly, internal cis-cyclic alkenes, which are challenging substrates in copper hydride-catalyzed
开发了喹啉和一水合乙酸铜(II)/(R,R)-Ph-BPE / P(对甲苯基)3-催化的对映选择性加氢胺化反应的1,2-还原脱芳香化反应,提供了多种4-氨基-1,具有高对映选择性的2,3,4-四氢喹啉,呈逐步或一锅方式。令人愉快的是,在氢化铜催化的对映选择性加氢胺化反应中具有挑战性的底物内部顺式环烯烃在温和条件下得到了有效转化。
