The efficient one-pot six-step domino process which occurs when (SS)-2-(p-tolylsulfinyl)-1,4-benzoquinone (1) reacts with 3,6-divinyl-1,2,7,8-tetrahydrophenanthrenes 2a–c allowed enantioselective access to [7]helicene bisquinones 3a–c with excellent optical purities (96 to > 99%
ee).
当(SS)-2-(对甲苯亚磺酰基)-1,4-苯醌(1)与 3,6-二乙烯基-1,2,7,8-四氢菲 2a-c 发生反应时,高效的一锅六步多米诺过程允许对映体选择性地获得[7]螺旋双醌 3a-c,并具有极佳的光学纯度(96% 至 > 99% ee)。
