Binaphthyl monoethyl ether

Chiral 1,1 -binaphthol derivatives are well established as readily available chiral catalysts and auxiliaries for the production of various useful optically active compounds. Tanabe et al. investigated [11] a crystalline-liquid resolution of (1R) -// . v - c h rysanthemic acid utilizing l,l -binaphthyl monoethyl ether (25) (Scheme 3).
