The synthesis of homochiral phosphorus-based ligands has escalated dramatically over the last decade in the drive to develop new, and further fine tune existing, base structures of chiral auxiliaries that have had, and most certainly are continuing to have, a phenomenal impact in the arena of enantioselective catalysis. This review highlights the vast array of homochiral phosphorus-based ligands and their significantly fewer arsenic-based analogs, the key synthetic strategies used to prepare them and the significant roles that they have been employed in after coordination to a transition metal center.

The one pot preparation of imidazolines from 1,2-cyclic sulfates is reported. Amidines react with cyclic sulfates to give zwitterionic intermediates, and subsequent intramolecular cyclization affords imidazolines. The preparation of enantiopure stilbene diamine (stien) is achieved by the hydrolysis of its corresponding chiral imidazoline.

Application of 19132-06-0, Chemical Research Letters, May 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic.

Two series of new enantiopure bidentate bis(diamidophosphite) ligands with diazaphospholidine and diazaphosphepine heterocyclic backbones were prepared. The ligands have a highly modular structure, which is well suited to the synthesis of a small library of compounds. Preparation was accomplished by the successive addition of enantiomerically pure substituted diamines (N,N?-dibenzylcyclohexane-1,2-diamine (1), N,N?-dimethylcyclohexane- 1,2-diamine (2), and N,N?-dimethyl-1,1?-binaphthyl-2,2?- diamine (3)) and enantiomerically pure diols (butanediol (a), cyclohexanediol (b), di-O-isopropylidenethreitol (c), and binaphthol (d)) to phosphorus trichloride. The corresponding bis(diamidophosphite) selenides were prepared, and the 1JPSe values were calculated in order to evaluate the sigma-donor ability of the new ligands. The cationic Rh(I) complexes [Rh(COD)(P,P)]BF4 were synthesized with 8 of the 12 new bis(diamidophosphite) ligands. The complexes were used as catalytic precursors for the asymmetric hydrogenation of benchmark substrates, namely methyl alpha-acetamidoacrylate (4), methyl (Z)-alpha-acetamidocinnamate (5), and dimethyl itaconate (6). The influence of the nature of both the terminal and bridging fragments of the bis(diamidophosphite) ligands on the asymmetric induction is discussed. Most proved to be effective catalysts for the process, attaining total conversion and excellent enantioselectivity (>99% ee) with the complex containing the (R;Ral,Ral;R)-3c ligand in the hydrogenation of the three substrates. The best performing catalytic precursor [Rh(COD)((R;Ral,Ral;R)-3c)]BF4 was tested in the hydrogenation of selected cyclic enamides (7-9) and beta-acetamidoacrylate (10).

Determination of the intrinsic noncovalent interactions governing chiral recognition in diastereomeric complexes constitutes the basis for understanding information transfer between molecules in living systems as well as in synthetic supramolecular structures. The most important experimental methodologies so far employed for this task are illustrated in the present review. Emphasis is put on the principles and the applications of techniques, such as radiolysis, Fourier transform ion cyclotron resonance (FTICR) and collision-induced dissociation (CID) mass spectrometry, and resonance-enhanced multiphoton ionization time-of-flight (REMPI-TOF) spectroscopy, that allow measurement of the relative stability of diastereomeric ion/molecule and molecule/molecule complexes and quantification of the short-range forces controlling their enantioselective evolution to products.

Syntheses of optically active acetylenic analogs of abscisic acid are described. The key step involves the diastereoselective alkylation of the (2S,3S)-butanediol ketal of oxoisophorone, which produces a 3:1 mixture of separable diastereoisomers. The absolute stereochemistry of the analogs was established by conversion to a known derivative and by correlation of ORD data.
