1Department of Chemistry, University of Utah, Salt Lake City, UT 84112-0850, USA.
A new gram-scale synthesis method for (R)-H 4-BINOL, a key ligand in asymmetric catalysis, has been developed. This method utilizes partial hydrogenation of BINOL after bis-etherification.
Area of Science:
- Organic Chemistry
- Asymmetric Catalysis
Background:
- Chiral BINOL derivatives are crucial ligands in asymmetric catalysis.
- Efficient synthesis of these ligands is essential for their broader application.
Purpose of the Study:
- To describe a gram-scale synthesis method for (R)-H 4-BINOL.
- To provide a reliable route for obtaining this important chiral ligand.
Main Methods:
- The synthesis involves bis-etherification of BINOL.
- A key step is the net partial hydrogenation of the bis-etherified BINOL.
Main Results:
- A scalable method for producing (R)-H 4-BINOL was established.
- The described procedure is amenable to gram-scale synthesis.
Conclusions:
- The developed method offers a practical route for gram-scale synthesis of (R)-H 4-BINOL.
- This facilitates the use of (R)-H 4-BINOL in asymmetric catalysis.

The reaction begins with transferring a proton from the acid catalyst to one of the hydroxyl groups, producing an oxonium ion.
Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.
