CAS 19902-08-0: beta-pinene

(1R,5R)-6,6-Dimethyl-2-methylene-bicyclo[3.1.1]Heptane is a deuterated geranyl compound that has been shown to have neuroprotective properties in animal models of Parkinson's disease and Alzheimer's disease. As a phosphite, it reacts with acids to form phosphoric acid and water. The acidic proton on the geranyl group can be protonated by protic solvents such as water and alcohols to form the corresponding alcoholate esters. This compound is biosynthesized from dietary sulfur, which contains sulfur atoms derived from sulfurous compounds such as hydrogen sulfide or cysteine (amino acid). The ligand has been rationalized through its similarity to fructus aurantii immaturus.
