Organocatalytic enantioselective [2π + 2σ] cycloaddition reactions of bicyclo[1.1.0]butanes with α,β-unsaturated aldehydes

Nature Communications
Bicyclo[2.1.1]hexanes (BCHs), three-dimensional benzene bioisosteres characterized by high sp3-carbon content, hold great promise for diverse applications in medicinal chemistry.

Circularly Polarized Polariton Lasing from Spin‐Momentum Locking in Deformed Plasmonic Kagome Cavities

Advanced Materials, EarlyView.
This paper describes room‐temperature polariton lasing with high circular polarization from deformed plasmonic Kagome lattice cavities strongly coupled to colloidal CdSe nanoplatelets. Spin‐selectivity from cavity modes resulted in control over the handedness of circular polarization as well as the direction of polariton lasing, opening prospects for ...

Facile access to bicyclo[2.1.1]hexanes by Lewis acid-catalyzed formal cycloaddition between silyl enol ethers and bicyclo[1.1.0]butanes

Nature Communications
Saturated three-dimensional carbocycles have gained increasing prominence in synthetic and medicinal chemistry. In particular, bicyclo[2.1.1]hexanes (BCHs) have been identified as the molecular replacement for benzenes.

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

Advanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Crystal structure, computational study, and Hirshfeld analysis of exo-1,2,3,5-tetraphenyl-1a',9b'-dihydrospiro[bicyclo[3.1.0]hexane-6,1′-cyclopropa[l]phenanthren]-2-en-4-one

Acta Crystallographica Section E: Crystallographic Communications
The reaction of dibenzonorcarynyliden(e/oid) with phencyclone was recently reported to give a congested spiropentane with endo stereochemistry. Herein we report that, in sharp contrast, an analogous reaction using tetracyclone, instead of phencyclone ...

Synthesis and Activity of Six-Membered Cyclic Alkyl Amino Carbene–Ruthenium Olefin Metathesis Catalysts [PDF]

, 2020
Ru–cyclic alkyl amino carbene (Ru–CAAC) olefin metathesis catalysts perform extraordinarily in metathesis macrocyclization and ethenolysis, but previous studies have been limited to the use of five-membered CAAC (CAAC-5) ligands.
