Application of 4254-15-3, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 4254-15-3, Name is (S)-Propane-1,2-diol,introducing its new discovery.
Highly regioselective primary etherification of racemic propane-1,2-diol by the tin(II) bromide-catalyzed reaction with diazo[bis(4-methoxyphenyl)]methane and the resolution of enantiomers with the help of Pseudomonas cepacia lipase
The tin(II) bromide-catalyzed reaction of diazo[bis(4-methoxyphenyl)]methane with racemic propane-1,2-diol in 1,2-dimethoxymethane resulted in the highly regioselective etherification of the primary hydroxyl group. After tritylation of the minor 2-ether, 1-[bis(4-methoxyphenyl)]methoxypropane-2-ol was obtained in pure form. The enantiomeric mono-ethers were resolved by kinetic resolution by transacetylation with the help of Pseudomonas cepacia lipase.
