Controlling orthogonal self-assembly through cis-trans isomerization of a non-covalent palladium complex dimer

The trans-configured square-planar complex of dichloropalladium and chiral monodentate phosphine ligands forms self-complementary dimers through 16 hydrogen bonded amides and pi-pi stacking in chlorinated solvents. The self-assembly is controlled by cis-trans isomerisation of the metal center, where the trans-configuration governs the dimer formation.

N,N-Disubstituted Allylic Amine Type Aminophosphines with C(aryl)-N(amine) Bond Axial Chirality: Synthesis and Application to Palladium-Catalyzed Asymmetric Allylic Alkylation with Malonates

We designed and synthesized a series of N,N-disubstituted allylic amine type aminophosphines 2, 3 and 4, which are derivatives of chiral ligands 1. Aminophosphines 2-4 (except 2a) exist in C(aryl)- N(amine) bond axial chirality by chiral HPLC analysis. Both enantiomeric isomers of 4b were successfully obtained in an enantiomerically pure form. We demonstrated that 1a, 1b, and 4b can be used as effective chiral ligands for the palladium-catalyzed asymmetric ally lie alkylation of 1,3-diphenyl-2-propenyl acetate with malonates in high enantioselectivities (up to 90% ee).

Photoinduced Syntheses and Reactivities of Phosphorus-Containing Interelement Compounds

The photoinduced reactions of tetraphenyl-diphosphine disulfide with a range of organic dichalcogenides successfully afforded a series of phosphorus(V)-chalcogen interelement compounds via a radical process. The relative reactivities of the organic dichalcogenides (i.e., (PhS)(2), (PhSe)(2), and (PhTe)(2)) toward the P-III or P-V groups in the diphosphine analogues under light were investigated in detail, and a convenient method was developed to form P-S or P-Se interelement compounds from tetraphenyldiphosphine disulfide and (PhS)(2) or (PhSe)(2) upon photoirradiation. Furthermore, the relative photochemical properties and reactivities of tetraphenyldiphophine (PP interelement compound) and its analogues toward photoinduced radical addition reactions were also discussed. The formed P-E (E = S, Se) interelement compounds could be utilized for ionic reactions, and they could be transformed into various phosphine reagents via one-pot processes.

Development of Quinoline-Derived Chiral Diaminocarbene Ligands and Their Transition Metal Complexes: Synthesis, Structural Characterization, and Catalytic Properties

N-Heterocyclic carbenes (NHCs) bearing a fused tricyclic skeleton have recently been developed as a new type of promising ligands for asymmetric transition metal catalysis. In this article, two kinds of chiral tricyclic NHCs featuring partially reduced 2,2′-bisquinoline- and 2-(piperidin-2-yl)quinoline skeleton have been prepared via a direct asymmetric hydrogenation synthetic strategy. Their Rh- and Pd-complexes were synthesized and characterized by NMR and high-resolution mass spectra as well as X-ray crystallography. The electronic effect and steric environment of these new chiral tricyclic NHCs were systematically evaluated by determining the Tolman electronic parameter (TEP) and the percent buried volumes (%V-bur) of the corresponding metalated complexes. It was revealed that these new ligands possess strong electron-donating properties and high steric demands. Additionally, these chiral NHC ligands have been successfully employed in the enantioselective palladium-catalyzed intramolecular alpha-arylation in high yield with good enantioselectivity (up to 80% ee). It is noteworthy that the rigid fused tricyclic rings and bulky ortho substituents can greatly improve the electron-donating property and chiral induction ability of these chiral NHC ligands.

The Binomial Copper-Catalysis and Asymmetric Ring Opening of Strained Heterocycles: Past and Future Challenges

This minireview is focused on the use of chiral copper-catalysts for the asymmetric ring opening of unsaturated strained heterocycles. Starting from the activity of my research group in Pisa over the years a report of the recent literature in this field is provided. From a mechanistic point of view the ring-opening reactions of unsaturated strained heterocycles with organometallic reagents are a sort of allylic alkylation in which the leaving group remains at the end of the reaction. Therefore, chiral ligands useful for copper-catalyzed asymmetric allylic alkylation and conjugate addition such as phosphoramidites and ferrocenyl phosphines have shown to be effective for ring-opening reactions as well. As consistently shown in the article, the regio- and stereoselectivities obtained with copper are in most cases complimentary to the selectivities attainable by other common metal catalysts such as palladium, nickel and rhodium. In recent years, the introduction of versatile boron atoms by the use of nucleophilic (chiral) copper-boryl complexes has enlarged considerably the synthetic potential of ring-opening reactions.
