The Golden Age of Biocatalysis: Combining Au(I) and enzymes – BiAuCat

Submission summary

Biocatalysis using enzymes for synthetic purpose has become accessible to synthetic chemists. Recently, the ?-transaminases, imine reductases or reductive aminases have enlarged the way to conceive the synthesis of chiral secondary amines and are even used at the industrial level. Among other enzymes, the so-called “Radical SAM enzymes” have emerged as a novel class of biocatalysts able to catalyze unprecedented chemical transformations, such as the alkylation of a variety of sp3- and sp2- carbon atoms, including the selective methylation at the position 2 of indole derivatives.

Cationic gold complexes are also efficient catalysts for the creation of C-C bonds. The spirocyclization of 2,3-disubstituted indoles tethered to unsaturations has emerged as a powerful approach for the access to potentially bioactive chiral spirocycles.

The BiAuCat project aims at combining the direct and selective functionalization of various indolic compounds using reductive aminases and/or radical SAM enzymes with the gold-catalyzed spirocyclizations using (chiral) Au(I) complexes. This innovative strategy will pave the way to new chiral spirocyclic derivatives through a sustainable approach.
