Recent Advances in Direct C-H Bond Functionalization of Phenylalanine Derivatives

Phenylalanine derivatives are widely found in a broad range of pharmaceutical molecules and exhibit significant biological activity. Direct C-H bond functionalization of phenylalanine derivatives to offer an efficient approach to construct C-I, C(sp(2))-C(sp(2)), C(sp(2))-C(sp), C(sp(2))-C(sp(3)), C-N, C-B and C-O bonds is described. The transformation involves ortho-C-H bond iodination and the following intramolecular amination, ortho-alkylation, ortho-arylation, ortho-alkenylation, ortho-alkynylation, ortho-acylation, ortho-acetoxylation, ortho-amination, ortho-boronation, meta-arylation and meta-alkylation.
