Asymmetric Synthesis of 2-Arylethylamines: A Metal-Free Review of the New Millennium.

2-Arylethylamines are presented in several natural bioactive compounds, as well as in nitrogen-containing drugs. Their ability to surpass the blood-brain barrier makes this family of compounds of especial interest in medicinal chemistry. Asymmetric methodologies towards the synthesis of 2-arylethylamine motives are of great interest due to the challenges they may present. Thus, a concise metal-free review presenting recent advances in the asymmetric synthesis of 2-arylethylamines is presented, covering last-millennium studies, considering different methodologies towards the aforementioned motif, including chiral induction, organocatalysis, organophotocatalysis and enzymatic catalysis.
