A Cu(II)-mediated synthesis of indolequinones from the corresponding bromoquinones and enamines is reported. The key oxidative cyclization proceeds in good yield for a broad range of substrates and can be performed on a multigram scale, allowing access to biologically interesting structures.
Gold-catalyzed cascade C–C and C–N bond formation: synthesis of polysubstituted indolequinones and pyrroles
The combination of Ph3PAuCl and AgOTf was proven to be an efficient catalyst for the cascade C–C and C–N bond formation reactions from enamines and bromoquinones or nitroolefins. This protocol affords a straightforward method for the synthesis of polysubstituted indolequinones and pyrroles in good yields.
