Facile asymmetric synthesis of L-Dopa and related amino acid esters has been achieved by phase-transfer catalysis of the rationally designed C 2 -symmetric chiral quaternary ammonium salts 1. The 'scale-up' experiment performed with 5.00 g of tert-butyl glycinate-benzophenone Schiff base (2) represe
