century, by activation of alcohols with activators, deoxygenative substitution of alcohols has been limited to employing nucleophiles with a single nucleophilic site. Herein, we demonstrate a fluoroolefin-mediated deoxygenative substitution of nonactivated and activated alcohols with diverse acidic nucleophiles, with inversion of configuration, to allow chemo- and enantiospecific construction of C–S, C–N
半个多世纪以来,通过用活化剂活化醇,醇的脱氧取代仅限于使用具有单个亲核位点的亲核试剂。在此,我们证明了氟代烯烃介导的非活化和活化醇与多种酸性亲核试剂的脱氧取代,并具有构型反转,以允许化学和对映特异性构建C-S、C-N、C-O和C-Se键通过区分亲核试剂的不同亲核位点。形成的O-束缚的单氟烯烃是中间体。
