This type of reactivity has quickly become one of the cornerstones of modern catalysis .In a patent, SDS of cas: 19132-06-0, name is (2S,3S)-Butane-2,3-diol, belongs to chiral-oxygen-ligands compound, introducing its new discovery. SDS of cas: 19132-06-0
A method for the synthesis of new chiral alpha/beta-dimethylamino esters and beta-amino ethers from (S,S)-hydrobenzoin is described. These new O,N-donor ligands are expected to prove a useful platform for exploring the relationship between the ligand structure and stereoselective direct aldol condensation catalyzed by their lanthanide complexes. The initial survey of the catalytic utility of newly synthesized complexes in the unique aldol-Tishchenko reaction of aldehydes and aliphatic ketones is also presented.
However, they have proven to be challenging because of the mutual inactivation of both catalysts. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 19132-06-0
