(S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol (cas: 863659-89-6) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Safety of (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol

Design of chiral tin(IV) aryloxide as a mild Lewis acid catalyst for enantioselective Diels-Alder reaction was written by Kano, Taichi;Konishi, Teppei;Konishi, Shunsuke;Maruoka, Keiji. And the article was included in Tetrahedron Letters in 2006.Safety of (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol This article mentions the following:

A novel Sn(IV) aryloxide Lewis acid was designed and prepared from SnCl4 and (S)-3,3′-bis[3,5-bis(trifluoromethyl)phenyl]-1,1′-bi-2-naphthol. The chiral Sn(IV) Lewis acid has been successfully applied to the enantioselective Diels-Alder reaction. In the experiment, the researchers used many compounds, for example, (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol (cas: 863659-89-6Safety of (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol).
