“…In last years a similar reaction were achieved can by either using other naphthols (Pirrone,1940) or quinolinols (Phillips,1956) or by replacing ammonia with alkyl amines (Brode & Littman, 1930), (Wang & Ding, 2002), (Cardellicchio et al, 1999) and (Szatmari, 2003). In addition, a variety of racemic structures related to the Betti's bases have been synthesized recently by addition of naphthols to the preformed imminium salts (Grumbach et al,1996). In recent years, the effort were done to synthesized the Betti's base derivatives in organic solvents such as EtOH, MeOH, and Et2O at room temperature or thermally under solvent less condition .The literature also reveals that such compounds are gaining interest of chemists who are working in the field of asymmetric synthesis because of utility in preparation of chiral inductors or chiral precursor.…”
