In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 2682-49-7, name is Thiazolidin-2-one, introducing its new discovery. Quality Control of Thiazolidin-2-one
Organocatalytic Cyclization of COS and Propargylic Derivatives to Value-Added Heterocyclic Compounds
The organocatalytic cyclization of propargylic amines/amides with carbonyl sulfide (COS) was firstly achieved by employing COS adducts of Lewis base (LB) as organocatalysts, affording various functionalized 1,3-thiazolidine-2-ones, and 1,3-thiazolidine-2,4-diones derivatives in a highly chemo- and stereoselective manner. The isotope labeling and stoichiometric experiments suggested the LB-COS adducts preferentially mediated basic ionic pair mechanism. Furthermore, the practical application of this methodology was highlighted by the highly efficient synthesis of rosiglitazone using COS as sulfur source.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 2682-49-7, and how the biochemistry of the body works.Quality Control of Thiazolidin-2-one
