Synthesis of novel bidentate P-chiral diaminophosphine oxide preligands: Application to Pd-catalyzed asymmetric allylic substitution reactions

We developed a novel (S)-L-phenylalanine derived-bidentate chiral diaminophosphine oxide (DIAPHOX) preligand (S,SP)-9b, which was successfully applied to Pd-catalyzed asymmetric allylic alkylation and amination. Using the Pd-(S,SP)-9b catalyst system, asymmetric allylic alkylation and amination proceeded very smoothly, affording the corresponding products in excellent yield with high enantiomeric excess. It is noteworthy that both enantiomers were accessible with high enantiomeric purity using the structurally related DIAPHOX preligands (S,SP)-9b and a monodentate chiral diaminophosphine oxide preligand (S,RP)-10a, both of which can be prepared from a single chiral source, (S)-L-phenylalanine.

Iterative deoxypropionate synthesis based on a copper-mediated directed allylic substitution

Can’t have too much of a good thing: A flexible, iterative strategy based on a highly selective copper-mediated allylic substitution makes the preparation of any desired oligo(deoxypropionate) stereoisomer possible (see scheme; RDG = reagent-directing group). This approach differs from the established enolate-alkylation methodology through the reversed polarity of the reaction partners and avoids several problems associated with the latter method.

Palladium-catalyzed Suzuki cross-coupling of aryl halides with aryl boronic acids in the presence of glucosamine-based phosphines

Carbohydrate-substituted phosphines are easily obtained in quite good yields by coupling of protected or non-protected d-glucosamine with the corresponding diphenylphosphino acid. These neutral ligands, in association with palladium acetate, are very active catalysts in the Suzuki cross-coupling reaction. The polyhydroxy phosphines are more active than the peracetylated phosphines. The process tolerates electron-rich as well as electron-poor substituents. Excellent turnovers, up to 97 000 are observed.

A highly sensitive and selective fluorescent probe for nitroxyl based on a naphthalene derivative

In this work, we developed a novel fluorescent probe 1 for quantitative detection of nitroxyl (HNO). Probe 1 consisted of a naphthalene backbone and 2-(diphenylphosphino)benzoate which was used as a nitroxyl recognition unit. The probe exhibited an intense fluorescence turn-on response to nitroxyl via aza-ylide formation and its subsequent Staudinger ligation to release compound 2. The probe can be applied to the quantification of nitroxyl with a linear range from 5.0 ¡Á 10-8 to 9.0 ¡Á 10-6 mol L-1. The detection limit of probe 1 toward nitroxyl was estimated to be 43 nM. Furthermore, probe 1 displayed a much higher selectivity for nitroxyl than other biologically relevant species. Importantly, owing to the high cell permeability and low cytotoxicity of probe 1, it was successfully applied to cell imaging of nitroxyl in living cells. The probe is expected to be a useful chemical tool for investigating the detailed functions and mechanisms of HNO in living systems.

Discovery of a robust and efficient homogeneous silver(I) catalyst for the cycloaddition of azides onto terminal alkynes

A highly efficient, chemically stable, and well-defined homogeneous silver(I) catalyst is reported for the cycloaddition of azides onto terminal alkynes (Ag-AAC reaction). The Ag-AAC reaction occurs at room temperature or with heating to deliver exclusively the corresponding 1,4-triazole. A pronounced ligand effect was discovered through systematic modification to the ligand structure resulting in the discovery of a chemically stable active catalyst for this reaction.

Allylic ruthenium(IV) complexes in catalysis

This review presents recent advances in the use of allylic ruthenium(IV) complexes as precatalysts in transition metal-catalyzed reactions. The topic is dominated by nucleophilic substitution reactions, where they appear either as initial catalysts or are generated upon oxidative addition of allylic substrates to ruthenium(II) precatalysts. Indeed, the general catalytic cycle describing this reaction is based on Ru(II)/Ru(IV) alternance. Other applications of allylic complexes, especially bis(allyl)Ru(IV) complexes in various catalytic transformations are also reported.
