Synthesis and Photophysical Properties of Naphtho[b]- and Indeno[b]-fused BODIPYs

A new synthetic method to construct [b]-fused BODIPY derivatives through PtCl2-catalyzed cycloisomerization reaction of peripherally phenylacetylene substituted BODIPYs is reported. Electron donating methoxy group facilitate both the 6-endo and

Diaryl acetylene compound containing methylene quinone as well as preparation method and application of diaryl acetylene compound

The invention discloses a diaryl acetylene compound containing methylene quinone as well as a preparation method and application thereof, and belongs to the technical field of pharmacy and chemical industry. The structural formula of the diarylacetylene c

Metal-Free Aminoiodination of Alkynes Under Visible Light Irradiation for the Construction of a Nitrogen-Containing Eight-Membered Ring System

A method for the synthesis of dihydrodibenzo[c,e]azocine derivatives via a regioselective intramolecular aminoiodination of alkynes under visible light irradiation has been developed. This protocol uses a combination of iodine and hypervalent iodine to re

Gold-Catalyzed Cascade and Divergent Synthesis of Indolobenzazepines and Indoloquinolines from Nitrogen-Tethered 1,8-Diynes

We describe the divergent construction of two nitrogen-containing polycyclic systems by gold-catalyzed cycloisomerizations. The gold-catalyzed cascade hydroamination and 7-endo-dig-selective cycloisomerization of nitrogen-tethered 1,8-diynes yielded indol

Concise synthesis of phospholene and its P-stereogenic derivatives

A simple method to build phospholene derivatives has been achieved in a one-pot reaction with readily available o-alkynylaryl bromides and alkylphosphine oxides. This method is also applicable to synthesize P-stereogenic phospholenes, and the resulting chiral phosphine was utilized as a ligand for coordination chemistry.

Electrophilic Cyanative Alkenylation of Arenes

A variety of appropriately substituted internal alkynes were transformed into the corresponding cyano-substituted phenanthrenes, dihydronaphthalenes, and cyclohepta-1,3,5-trienes in moderate to excellent yields by treatment with imidazolium thiocyanate 1, which serves as an easy to handle [CN]+ precursor, in the presence of BCl3. The synthetic value of the method is additionally demonstrated by the transformation of the primarily obtained products into heavily substituted quinolines. Additionally, the dynamic properties of the prepared dibenzocyclohepta-1,3,5-trienes have been investigated.

Remote sp2C-H Carboxylation via Catalytic 1,4-Ni Migration with CO2

A remote catalytic reductive sp2 C-H carboxylation of arenes with CO2 (1 bar) via 1,4-Ni migration is disclosed. This protocol constitutes the first catalytic 1,4-Ni migration reported to date, thus offering new vistas in the Ni-catalyzed reductive coupling arena while providing an unconventional new platform for incorporating electrophilic sites at remote sp2 C-H linkages.

Enantioselective Synthesis of 1-Aryl Benzo[5]helicenes Using BINOL-Derived Cationic Phosphonites as Ancillary Ligands

The synthesis of unprecedented BINOL-derived cationic phosphonites is described. Through the use of these phosphanes as ancillary ligands in AuI catalysis, a highly regio- and enantioselective assembly of appropriately designed alkynes into 1-(

Domino Palladium-Catalyzed Double Norbornene Insertion/Annulation Reaction: Expeditious Synthesis of Overcrowded Tetrasubstituted Olefins

A Pd-catalyzed domino process involving a double norbornene insertion/annulation reaction was developed for the expeditious synthesis of overcrowded olefins. In this one-pot reaction, four new C-C bond formations were achieved by three consecutive Heck ca

Controlling the Selectivity Patterns of Au-Catalyzed Cyclization-Migration Reactions

As little as 2 mol % of (XPhos)AuNTf2 catalyzes the transformation of a broad range of o-acetylene-substituted styrenes into 1,2-dihydronaphthalenes. Our data suggests that this transformation occurs via a gold-stabilized cyclopropyl carbinyl cation, which triggers either a [1,2] carboxylate shift or a less favorable [1,2] aryl shift. The relative rates of these migrations can be controlled by the identity of the ligand or by stabilizing the mesomeric cation.
