(R,R)-(+)-HYDROBENZOIN Chemical Properties,Usage,Production

Chemical Properties

white to beige or light brown crystalline powder

Uses

(R,R)-(+)-Hydrobenzoin may be used in the oxyselenenylation step in the multi-step synthesis of cyclopentitols and aminocyclopentitols from cyclopentene. It may also be used as a ligand for the asymmetric addition of diethylzinc to aldehydes in the presence or absence of titanium tetra-isopropoxide to form (R)- or (S)-form of the corresponding secondary alcohol, respectively.

Definition

ChEBI: (R,R)-hydrobenzoin is a hydrobenzoin.

General Description

(R,R)-(+)-Hydrobenzoin is a chiral 1,2-diol useful as a chiral reagent, building block, ligand or auxiliary in asymmetric synthesis.
