Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 51805-45-9, Name is 3,3′,3”-Phosphinetriyltripropanoic acid hydrochloride, molecular formula is C9H16ClO6P, belongs to chiral-phosphine-ligands compound. In a document, author is Musina, Elvira, introduce the new discover, Quality Control of 3,3′,3”-Phosphinetriyltripropanoic acid hydrochloride.
Self-Assembly of Chiral 1,8-Diaza-3,6,10,13-tetraphosphacyclotetradecanes via Dynamic Transformation of 7-and 14-Membered Aminomethylphosphines
Chiral 1,8-diaza-3,6,10,13-tetraphosphacyclotetradecanes were obtained by condensation of 1,2-bis(phenylphosphanyl)ethane, paraformaldehyde and optically pure (S)-(+)-sec-butylamine or racemic sec-butylamine. The covalent self-assembly stereoselectively led to only one enantiomer, 14-(P4C2SS)-C-SSSS, starting with the optically pure sec-butylamine, and to two enantiomeric pairs, 14-(P4C2SS)-C-SSSS/14-P4 (R) C2 (R) and 14-(P4C2RS)-C-SSSS/14-P4 (R) C2RS, when employing the racemic sec-butylamine. It was demonstrated that all stereoisomers undergo dynamic transformation into three diastereomers of 7-membered cycles: two stereoisomers with the same configuration (rac) and one isomer with different configuration of the phosphorus atoms (meso form) of both phosphorus atoms.
