A nickel-catalyzed reductive cyclization of enones affords a wide array of indanones in high enantiomeric induction. The reaction is featured with an unprecedented broad scope of substrates. The versatility of the new method is demonstrated in several short stereoselective syntheses of medically valuable (R)-tolterodine, parent and deuterated (+)-indatraline, and an antitumor natural product, (+)-multisianthol
镍催化的烯酮的还原环化在高对映异构体诱导下提供了多种茚满酮。该反应具有前所未有的广泛底物范围。新方法的多功能性在医学上有价值的(R)-托特罗定,母体和氘代(+)-茚达林以及抗肿瘤天然产物(+)-multisianthol的几种短时立体选择性合成中得到了证明。相比之下,这些化合物不能通过钯催化的类似方法令人满意地制备。
