(S)-(-)-1,1'-Bi-2-naphthol Chemical Properties,Usage,Production

Chemical Properties

white to light yellow crystal powde

Uses

(S)-BINOL ligand in combination with titanium(IV) isopropoxide, forms (S)-(-)-BINOL-Ti complex, which is an effective chiral catalyst for:

  • asymmetric addition of alkynylzinc to unactivated ketones
  • enantioselective ring-opening reaction of meso-stilbene oxide and cyclohexene oxide with anilines
  • asymmetric aryl transfers from triaryl(tetrahydrofuran)aluminum reagents to a wide variety of ketones
It can also react with zirconium(IV) isopropoxide isopropanol complex to form a chiral Lewis acid catalyst for the facile enantioselective allylation of aldehydes by allyltributyltin.

Uses

Chiral ligand.

Definition

ChEBI: (S)-(-)-1,1'-Bi-2-naphthol is a member of naphthols.

Purification Methods

Dissolve it in cold 2.5N NaOH, extract with CH2Cl2, and acidify with 5% HCl. Collect the white precipitate and recrystallise it from aqueous EtOH and dry it in a vacuum [Akimoto & Yamada Tetrahedron 27 5999 1971]. It is optically stable in dioxane-water (100o/24hours). Racemisation: 72% in 1.2N HCl at 100o/24hours and 68% in 0.67M KOH in BuOH at 118o/23hours [Kyba et al. J Am Chem Soc 95 2693 1973]. It has also been crystallised from *C6H6 (solubility is 1%) using Norite or aqueous EtOH after chromatography through silica gel, eluting with Me2CO/*C6H6. [Kyba et al. J Org Chem 42 4173 1977; see also Brussee & Jansen Tetrahedron Lett 24 3261 1983, Akimoto & Yamada Tetrahedron 27 5999 1971, Beilstein 6 IV 7020.]
