Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 541-14-0, Name is (S)-3-Hydroxy-4-(trimethylammonio)butanoate, molecular formula is C7H15NO3, belongs to chiral-catalyst compound. In a document, author is Wang, Wenyao, introduce the new discover, Safety of (S)-3-Hydroxy-4-(trimethylammonio)butanoate.
A catalytic asymmetric sequential annulation/aldol reaction of 4-isothiocyanato pyrazolones and allenyl ketones has been developed, which furnished a series of spiro[pyrrole-pyrazolone] heterocycles and structurally novel spiro[thiopyranopyrrole-pyrazolone] derivatives in good yields with high to excellent enantioselectivities. Notably, parallel resolution of racemic spiro[pyrrole-pyrazolones] was achieved by a catalyst-controlled asymmetric intramolecular vinylogous aldol process. Structure diversity of the product was further enhanced by ready transformations.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 541-14-0. Safety of (S)-3-Hydroxy-4-(trimethylammonio)butanoate.
