Synthesis of novel chiral thiophene-, benzothiophene- and benzofuran-oxazoline ligands and their use in the enantioselective Pd-catalyzed allylation

Novel thiophene, benzothiophene and benzofuran-oxazoline ligands 6-11 containing a diphenylphosphino group at different positions of the heterocyclic skeleton have been prepared and used in the enantioselective allylation. The advantage of these new ligands is their easy accessibility and their high reactivity. The best results were obtained with ligand 9 to give the product 13 in 97.0% ee with 92% yield in 2 hours at 0C.

One-Pot Protocol to Synthesize 2-Aminophenols from Anilines via Palladium-Catalyzed C-H Acetoxylation

This paper describes a facile one-pot protocol to synthesize 2-aminophenol derivatives via a palladium-catalyzed C-H acetoxylation strategy with 5-nitropyrimidine as a directing group (DG), which can be easily preinstalled and readily removed under mild condition after the coupling. In addition, the transformation is operationally simple, has high functional group tolerance, and is amenable to gram-scale. Moreover, several examples were shown that introduction/removal of 5-nitropyrimidine and the C-H oxylation sequence could be integrated in one pot.

Single-Electron Transmetalation: Photoredox/Nickel Dual Catalytic Cross-Coupling of Secondary Alkyl beta-Trifluoroboratoketones and -esters with Aryl Bromides

The first cross-coupling of secondary alkyl beta-trifluoroboratoketones and -esters has been achieved through application of photoredox/nickel dual catalysis. Although the related beta-trifluoroboratoamides have been effectively cross-coupled via Pd-catalysis, the corresponding ketones and esters had proven recalcitrant prior to this report. Reactions occur under mild conditions, and a variety of functional groups and sterically and electronically diverse reaction partners are tolerated.

Catalytic Diastereo- and Enantioselective Fluoroamination of Alkenes

The stereoselective synthesis of syn-beta-fluoroaziridine building blocks via chiral aryl iodide-catalyzed fluorination of allylic amines is reported. The method employs HF-pyridine as a nucleophilic fluoride source together with mCPBA as a stoichiometric oxidant, and affords access to arylethylamine derivatives featuring fluorine-containing stereocenters in high diastereo- and enantioselectivity. Catalyst-controlled diastereoselectivity in the fluorination of chiral allylic amines enabled the preparation of highly enantioenriched 1,3-difluoro-2-amines bearing three contiguous stereocenters. The enantioselective catalytic method was applied successfully to other classes of multifunctional alkene substrates to afford anti-beta-fluoropyrrolidines, as well as a variety of 1,2-oxyfluorinated products.

Acid-base-responsive intense charge-transfer emission in donor-acceptor-conjugated fluorophores

Herein we report on the synthesis and acid-responsive emission properties of donor-acceptor (D-A) molecules that contain a thienothiophene unit. 2-Arylthieno[3,2-b]thiophenes were conjugated with an N-methylbenzimidazole unit to form acid-responsive D-A-type fluorophores. The D-A-conjugated fluorophores showed intense intramolecular charge-transfer (ICT) emission in response to acid. The effect of the substitution on their photophysical properties as well as their solvent-dependence indicated non-twisting ICT emission in protonated D-A molecules. The quinoidal character of 2-arylthienothiophene as a donor part is discussed, as it is assumed that it contributes to suppression of the molecular twisting in the excited state, therefore decreasing the nonradiative rate constant, thereby resulting in the intense ICT emission. Acid-base-sensitive triple-color emission was also achieved by the introduction of a base-responsive phenol group in the donor part.

Catalytic [2 + 2 + 2] cycloaddition of benzothiophene dioxides with alpha,omega-diynes for the synthesis of condensed polycyclic compounds

A Rh-catalyzed intermolecular [2 + 2 + 2] cycloaddition of the 2,3-double bond of benzothiophene dioxides with alpha,omega-diynes gave sulfone-containing cycloadducts in high yields. This is the first example of a catalytic [2 + 2 + 2] cycloaddition that uses the 2,3-double bond of a heterole as an ene moiety. The consecutive reaction of benzodithiophene tetraoxide with 2,3-naphthylene-tethered 1,7-diyne gave an 11-ring condensed polycyclic compound in one pot.
