Catalytic Enantioselective Synthesis of C (1)‐ and C (2)‐Symmetric Spirobiindanones through Counterion‐Directed Enolate C‐Acylation
A catalytic enantioselective route to C(1)‐ and C(2)‐symmetric 2,2′‐spirobiindanones has been realized through an intramolecular enolate C‐acylation. This reaction employs a chiral ammonium counterion to direct the acylation of an in situ generated ketone enolate with a pentafluorophenyl ester. This...
