Synthetic Route of 24621-61-2, New discoveries in chemical research and development in 2021. In homogeneous catalysis, catalysts are in the same phase as the reactants. A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes. 24621-61-2, Name is (S)-Butane-1,3-diol, molecular formula is C4H10O2. belongs to chiral-oxygen-ligands compounds. In a Article，once mentioned of 24621-61-2
The hydrolytic dehalogenation of rac-1,3-dibromobutane catalyzed by the haloalkane dehalogenase LinB from Sphingobium japonicum UT26 proceeds in a sequential fashion: initial formation of intermediate haloalcohols followed by a second hydrolytic step to produce the final diol. Detailed investigation of the course of the reaction revealed favored nucleophilic displacement of the sec-halogen in the first hydrolytic event with pronounced R enantioselectivity. The second hydrolysis step proceeded with a regioselectivity switch at the primary position, with preference for the S enantiomer. Because of complex competition between all eight possible reactions, intermediate haloalcohols formed with moderate to good ee ((S)-4-bromobutan-2-ol: up to 87 %). Similarly, (S)-butane-1,3-diol was formed at a maximum ee of 35 % before full hydrolysis furnished the racemic diol product.
