Syntheses and Transformations of 1-(α-Aminobenzyl)-2-Naphthol Derivatives

The syntheses and transformations of 1-(α-aminobenzyl)-2-naphthol (Betti base) derivatives are reviewed. Special attention is paid to the applications of enantiopure Betti base derivatives as chiral ligands in asymmetric transformations. Keywords: aminonaphthols, betti base, naphthoxazines, tautomerism
