Corrigendum to “Enantioselective alkylation and protonation of prochiral enolates in the asymmetric synthesis of β-amino acids” [Tetrahedron 59 (2003) 4223]

This paper describes work that corrects the synthetic procedures reported in the title paper for the preparation of novel chiral phenolic acids , , and . Unlike the results provided in the article being reexamined, protonation of prochiral enolates -Li and -Li with chiral Brønsted acids proceeded with negligible enantioselectivity.
