Article Abstract

Three-dimensional alicyclic skeletons with multiple stereochemically defined chiral centers are highly valuable in modern drug discovery. Here, we reported a diverse approach to access 1,2- and 1,3-disubstituted chiral cycloalkanes by the strategy of NiH-catalyzed, transannular-directed alkene desymmetrization. The ring strain of the bridged bicyclic organonickel intermediate and the coordination effect of the ligand were identified as crucial factors in determining site selectivity by influencing the NiH migration step. This methodology demonstrates a broad substrate scope and displays good tolerance toward various functional groups, resulting in excellent outcomes in terms of the yield, regioselectivity, and enantioselectivity.

We report on the synthesis and self-assembly of 2,15- and 4,13-disubstituted carbo[6]helicenes and bearing 3,4,5-tridodecyloxybenzamide groups. The self-assembly of these [6]helicenes is strongly influenced by the substitution pattern in the helicene core that affects the mutual orientation of the monomeric units in the aggregated form. Thus, the 2,15-substituted derivative undergoes an isodesmic supramolecular polymerization forming globular nanoparticles that maintain circularly polarized light (CPL) with values as high as 2 × 10.

A highly enantioselective synthesis of 5,13-disubstituted dibenzo[d,d']benzo[1,2-b:4,3-b']dithiophenes is reported. Key for the successful assembly of these helical architectures is the last two successive Au-catalyzed intramolecular alkyne hydroarylation events. Specifically, the second cyclization is the enantiodetermining step of the whole process and provides the desired helicenes with excellent ee values when a TADDOL-derived 1,2,3-(triazolium)phosphonite moiety (TADDOL: α,α,α',α'-tetraaryl-1,3-dioxolane-4,5-dimethanol) is employed as an ancillary ligand.

Two new families of porphyrins with mixed substituent pattern, viz. 2-nitro-12,13-disubstituted-meso-tetraphenylporphyrins (H2TPP(NO2)X2, X = Ph, phenylethynyl (PE), 2-thienyl (Th), Br, and CN) and 2-nitro-7,8,12,13,17,18-hexasubstituted-meso-tetraphenylporphyrins (H2TPP(NO2)X6, X = Br, Ph, PE, and Th), and their metal (Co(II), Ni(II), Cu(II), and Zn(II)) complexes have been synthesized and characterized. H2TPP(NO2)X6 exhibited remarkable red shift in the Soret band (45-70 nm) and longest wavelength band, Qx(0,0) (65-90 nm), as compared to H2TPP(NO2).

Computational and experimental studies have been performed to investigate the photostability of a series of 6,13-bis(arylalkynyl)-substituted pentacenes in the presence of oxygen. These studies indicate that photostabilization occurs through a selective LUMO orbital stabilization as has been seen previously for 6,13-bis(triisopropylsilylethynyl)pentacene. Marcus theory analysis suggests that the difference in vibrational reorganization energies across all compounds is small and that the thermodynamic driving force for forward electron transfer is primarily responsible for the observed photostabilization.

Article Synopsis
  • - The study details the synthesis of novel compounds known as 4,9-methanoundecafulvene derivatives (10a-c) and their structural analysis using NMR and UV-vis spectroscopy.
  • - Upon treatment with DDQ, these derivatives undergo oxidative cyclization to form stable cationic products (11a-c*BF4-) with well-defined spectroscopic properties and confirmed structure through X-ray crystallography.
  • - The cations showed low reducibility and exhibited selective nucleophilic reactions, as well as successful photoinduced oxidation reactions that yielded more than 100% of the target carbonyl compounds.
