Direct α-C(sp3)-H alkylation of hydroaminoalkylation (HAA) catalyzed by tBuOK/DMSO/O2 from α-aryl benzylamines with styrenes is reported. The reaction has delivered diverse selectively substituted amines and N-heterocycles under mild conditions. Mechanism studies have shown that α-aminoalkyl ...

Interest-ingly,pyrroles 5 remained absolutely inert in this reaction and were recovered without apparent loss. We believe that the mechanism of the formation of4,5-dihydro-3H-azepines 1 and 3H-azepines 2 in our case corresponds to that depicted in Scheme of Table 2. Indeed, the ...
