experimental determination of solubility and ternary phase diagram of chiral compound are of tedious and time consuming tasks, and in many cases, there is not enough experimental data for different enantiomeric compositions to access the experimental ternary phase diagram. using thermodynamic models with predictive capability, having less dependency on experimental data, affords a great advanta...

The first asymmetric total synthesis of psychotrimine, a trimeric indole alkaloid, was accomplished via an asymmetric Ireland-Claisen rearrangement to construct a chiral quaternary carbon center, thereby establishing the absolute configuration of psychotrimine.

The enzyme OPAA hydrolyzes p-nitrophenyl phosphotriesters bearing substituents at the phosphorus center ranging in size from methyl to phenyl. The enzyme exhibits stereoselectivity toward the hydrolysis of chiral substrates with a preference for the Sp enantiomer.

C3-Symmetric chiral trisimidazolines with m-chloroperbenzoic acid promoted the organocatalytic oxidation of N-sulfonyl ketimine. The present imidazoline catalysis produced oxaziridines bearing a tetrasubstituted carbon stereogenic center in high yields with up to 87% ee.

Free radical polymerization of (+)-2,5-bis[4'-((S)-2-methylbutyloxy)phenyl]styrene yields a chiral polymer with memory of optical activity after the initial stereogenic center in the side group of the monomer is chemically removed.

The 4-oxofurofuran lignan, (+)-aptosimon (1), was synthesized from gamma-butyrolactone (9). To construct the two benzylic chiral center of (+)-aptosimon (1), highly erythro selective aldol condensation and stereoconvergent SN1 intramolecular cyclization were used as the key reactions.

A porous homochiral MOF was constructed from a serine derivate ligand bridged and chelated copper atom subunit, which can expand one chiral center into multitopic homochiral centers to systematically tune the heterogeneous catalytic properties.

The title compound, C(13)H(11)BrO(2), contains a tricyclic ring system with one chiral center which exhibits an R configuration. The crystal structure is devoid of any classical hydrogen bonding.

Axial and center chirality of Pd complexes with tropos biphenyl secondary diamine ligands is shown to be controlled by chiral amide (R)-DABNTf, which can efficiently discriminate between two enantiomeric Pd complexes.
