Gold Catalysis Coupled with Visible Light Stimulation: Syntheses of Functionalized Indoles
摘要:
A judicious combination of Au-catalysis and synergistic visible-light stimulation formulates an exceptionally simple and mild reaction system capable of directly coupling anilines and alkynes to form multifunctionalized indoles.
A highly selective sp3 C–N cleavage of tertiary anilines was achieved using the TBN/TEMPO catalyst system. When N,N-diaklylanilines (alkyl, benzyl) were employed, the N–CH3 bond was selectively cleaved via radical C–Hactivation. Moreover, when the allyl group was installed, totally reverse selectivity was observed. It is worth noting that the solvent effect is also crucial to obtain high reaction
