(S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol (cas: 863659-89-6) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Synthetic Route of C40H26O2

Binaphthol-derived phosphoric acids as efficient organocatalysts for the controlled ring-opening polymerization of γ-benzyl-L-glutamate N-carboxyanhydrides was written by Liang, Jinpeng;Zhi, Xinmei;Zhou, Qiwen;Yang, Jing. And the article was included in Polymer in 2019.Synthetic Route of C40H26O2 This article mentions the following:

Despite great progress, it is still one attractive topic to explore new controlled ring-opening polymerization method to fabricate well-defined polypeptides. Considering the activation of organophosphates and the polymerization characteristics of N-carboxyanhydrides (NCA), we herein describe an effective (S)-1,1′-binaphthyl-based phosphoric acid catalytic system that mediates controlled ring-opening polymerization (ROP) of γ-benzyl-L-glutamate N-carboxy-anhydrides (BLG-NCA) with primary amines as initiator. In the presence of (S)-2,2′-dimethoxyl-1,1′-binaphthyl phosphoric acid ((S)-1e), ROP with various feeding ratios of BLG-NCA to initiator afforded poly(γ-benzyl-L-glutamate) (PBLG) with expected mol. weights (5.0-32.7 kg/mol) and relatively narrow dispersities (Mw/Mn = 1.05-1.16). The kinetics and chain extension experiments were conducted to identify that (S)-1e-catalyzed ROP of BLG-NCA in a controlled/living manner. A probable interaction between (S)-1e and the amine group of initiator/polymer chain-end was verified from 1H NMR, 31P NMR experiments A plausible phosphate-ammonium mode catalyzing ROP of BLG-NCA was discussed. In the experiment, the researchers used many compounds, for example, (S)-[2,3′:1′,1”:3”,2”’-Quaternaphthalene]-2′,2”-diol (cas: 863659-89-6Synthetic Route of C40H26O2).
