Synthesis of aromatic alpha-aminoesters: Palladium-catalyzed long-range arylation of primary Csp3-H bonds

Remote control: The title reaction for beta-Izeta arylation of alpha-amino esters with aryl bromides is described. This reaction, which occurs selectively at the terminal position of linear alkyl chains, gives rise to synthetically useful (hetero)arylalanines and homologues after debenzylation (see scheme).

Synthesis and Application of Planar Chiral Cyclic (Amino)(ferrocenyl)carbene Ligands Bearing FeCp? Group

New cyclic (amino)(ferrocenyl)carbene (CAFeC) ligands containing the Cp? group have been developed as a modification of their prototype Cp version. The generation of the new carbenes was indirectly confirmed by trapping experiments in which a carbene precursor was reacted with sulfur or [IrCl(cod)]2 in the presence of a base. The electronic properties of the new CAFeCs were evaluated by determining the Tolman electronic parameter (TEP) of the Ir dicarbonyl complex [IrCl(CO)2(CAFeC)] that was synthesized via [IrCl(cod)(CAFeC)]. It was revealed that the donor strengths of the new CAFeCs were very high and comparable to those of cyclic (amino)(alkyl)carbenes (CAACs). The influence of the steric effect on the enantioselectivity by changing Cp to the Cp? group of CAFeCs was confirmed to be significant in an Ir-catalyzed asymmetric transfer hydrogenation of cyclic N-sulfonylimine where CAFeCs were used as chiral ligands.

Heterometallic iodoplumbates modified by copper(I) or silver(I) with viologens

Cu/Ag(I) were introduced into iodoplumbate systems to produce two new heterometallic iodoplumbates with viologen as templates, i.e. (PV)2(Pb2Cu2I10) (1) and [(BV)(Pb2AgI7)]n (2) (PV2+?=?propyl viologen, BV2+?=?benzyl viologen), in which the common connection of PbI6 units have been remarkably altered. In (PV)2(Pb2Cu2I10) (1), two PbI6 octahedra are bridged by two CuI4 tetrahedra via face-sharing to give a (Pb2Cu2I10)4? cluster, but the ternary one-dimensional polymeric (Pb2AgI7)n 2n? of [(BV)(Pb2AgI7)]n (2) is assembled from edge-sharing AgI4 tetrahedra and PbI6 octahedra. Their optical band gaps and fluorescence were also discussed. The absorption edges of haloplumbates could be engineered by introduction of suitable conjugated molecules as templates.

Regiodivergent Ring-Opening Cross-Coupling of Vinyl Aziridines with Phosphorus Nucleophiles: Access to Phosphorus-Containing Amino Acid Derivatives

Catalytic ring-opening phosphonation and phosphatation of vinyl aziridines have been developed in a regiodivergent fashion, giving linear and branched products. Generation of P-centered radicals enables SN2?-type ring-opening reactions of vinyl aziridines to afford delta-amino alkylphosphorus products at room temperature. On the other hand, in situ generated phosphate anions via the Ag-catalyzed aerobic oxidation of phosphonyl reactants underwent SN2 reaction to provide branched phosphorus-containing amine products. Furthermore, this divergent methodology serves as a powerful tool for the stereospecific synthesis of phosphorus-containing amino acid derivatives.
