A new class of bisphosphine ligands (5, 6) with a cyclobutane backbone have been designed and synthesized on the basis of a privileged C2 scaffold of head-to-head coumarin dimer, among which ligand 5a was found to show excellent activity and enantioselectivity in Pd-catalyzed desymmetrization of the biscarbamate of meso-cyclopent-2-en-1,4-diol, affording oxazolidin-2-one in up to 90% yield with 97% ee.

In a Article，once mentioned of 17261-28-8, Computed Properties of C19H15O2P

The combined usage of two bioorthogonal reactions can provide hetero-bifunctional molecules under physiological conditions for various applications. Based on the Nonhydrolysis Staudinger Reaction (NSR), we design and develop a bisazido linker 1 for chemoselective dual-functionalization without the need of protection using catalyst-free and one-pot procedures. The NSR is much faster with tetrafluorinated aromatic azide than that the Staudinger-Bertozzi or SPAAC ligation with alkyl azide, as revealed by HPLC analysis and fluorescence kinetics. Based on the tandem NSR and Staudinger-Bertozzi ligation, we prepare a molecular beacon 7 from 1 in one-pot synthesis with a recovery yield of 32%. When a faster SPAAC ligation is used instead of the Staudinger-Bertozzi ligation, compound 8 is prepared in the tandem NSR and SPAAC reactions with a recovery yield of 59%. As a proof-of-concept study, the tandem NSR and SPAAC ligation is further used to produce a FRET-based dyad in living cells, as revealed by dual-color bioimaging. This work shows that NSR can be combined with other bioorthogonal reactions without the need of protection in one-pot.

A series of triphenylphosphinecarboxamide (TPPc) derivatives were designed and synthesized as alternative reagents to triphenylphosphine for the facile reduction of azides. The TPPc derivatives performed as efficient reducing agents for the synthesis of primary amines without the need for an additional hydrolysis procedure. The TPPc derivatives were also applied to nucleic acid sensing using a RhAz-oligonucleotide conjugate in a DNA-templated fluorogenic reaction.

New methodology for the stereoselective synthesis of trisubstituted olefins is presented. The use of ortho-diphenylphosphanyl benzoate (o-DPPB) as a directing leaving group for copper-mediated allylic substitution with Grignard reagents allowed for the stereoselective construction of a wide range of E olefins, without the need for an adjacent electron-withdrawing group. Our modular three-step approach toward trisubstituted alkenes commenced with geminal alpha-methylene aldehydes. Addition of an organometallic reagent and introduction of the o-DPPB group by esterification was followed by the o-DPPB-directed copper-mediated allylic substitution with a Grignard reagent to furnish stereodefined trisubstituted olefins. Additionally, incorporation of a stereocenter from the chiral pool allowed the preparation of an enantiomerically pure olefin that bore three alkyl substituents in high E/Z selectivity.

A FRET-based two-photon fluorescent probe, P-Np-Rhod, which exhibited a fast and high selective ratiometric response to nitroxyl, was first proposed. P-Np-Rhod was successfully applied to two-photon dual-channel imaging of nitroxyl in living cells and tissues with less cross-talk between channels and satisfactory deep-tissue imaging depth.

By what means and how well can axial chirality be controlled in an intermolecular Suzuki biaryl cross-coupling reaction? The directionality of reductive elimination [Eq.(1)] is completely controlled by using a strategically positioned internal ligand L to afford a single biaryl atropisomer corresponding to the korupensamine A skeleton.

Metal-directed supramolecular construction represents one of the most powerful tools to prepare a large variety of structures and functions. The ability of metals to organize different numbers and types of ligands with a variety of geometries (linear, trigonal, octahedral, etc.) expands the supramolecular synthetic architecture. We describe here the precise construction of homo- and heterodimeric cyclic peptide entities through coordination of a metal (Pd, Au) and to beta-sheet-type hydrogen-bonding interactions. The selective coordination properties of the appropriate metal allow control over the cross-strand interaction between the two-peptide strands. Metal tweezers: The self-assembling properties of alpha,gamma-cyclic peptides are reinforced by metal coordination to precisely construct homo- and heterodimeric complexes. The metal coordination is able to shift the equilibrium from several nonequivalent dimers to one single ensemble (see scheme). Copyright

Ligands useful for transition metal catalyzed bond forming reactions are provided with a metal binding portion having at least one metal binding moiety STR1 wherein Ar and Ar’ each is an aryl or a heteroaryl. These ligands may be prepared by providing an aromatic carboxylic acid having a diarylphosphino or diheteroarylphosphino substituent on the aromatic ring, and forming an ester or an amide derivative of the carboxylic acid by coupling with a chiral diol or a chiral diamine. The ligands facilitate, for example, flexible strategies for enantiocontrolled construction of five membered carbocyclic rings with varying substitution patterns and high enantioselectivity.
