Enantioselective Total Syntheses of Lyconadins A?E through a Palladium-Catalyzed Heck-Type Reaction

A novel palladium-catalyzed Heck-type reaction of thiocarbamates has been designed to construct bridged seven-membered-ring systems that are otherwise challenging to prepare. Taking advantage of this newly developed method, enantioselective syntheses of lyconadins A?E (1?5), lycopecurine (6), and dehydrolycopecurine (7) have been realized in a divergent fashion. Our synthetic strategy also features an intramolecular cyclization of a N-chloroamine to forge the C6?N bond, a transannular Mannich-type reaction of a cyclic nitrone to stitch the C4 and C13 together, and a cyclocondensation to deliver the (dihydro-)pyridone motif.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 12131-44-1, you can also check out more blogs about12131-44-1

We report a procedure to linearly scale-up the synthesis of 2,8-bis(3,6-di-tert-butyl-9H-carbazol-9-yl)dibenzothiophene-S,S-dioxide (compound 4) and 2,8-bis(10H-phenothiazin-10-yl)dibenzothiophene-S,S-dioxide (compound 5) using Buchwald-Hartwig cross-coupling reaction conditions. In addition, we demonstrate a scaled-up synthesis of all non-commercially available starting materials that are required for the amination cross-coupling reaction. In the present article, we provide the detailed synthetic procedures for all of the described compounds, alongside their spectral characterization. This work shows the possibility to produce organic molecules for optoelectronic applications on a large scale, which facilitates their implementation into real world devices.

Lariat ethers with fluoroaryl side-arms: A study of CF…metal cation interaction in the complexes of N-(o-fluoroaryl)azacrown ethers

New lariat ethers, N-(o-fluorophenyl)aza-15-crown-5 (F-A15C5) and N,N?-bis(o-fluorophenyl)diaza-18-crown-6 (F2-A 218C6), were prepared by the N-arylation of the corresponding azacrown ethers. The interaction of the ligands with metal cations was studied in solution by 1H and 19F NMR (in acetone-d6) and UV spectroscopy (MeOH) confirming the formation of complexes of F 2-A218C6 with K+, Na+, Ag +, Ba2+, Pb2+ and of F-A15C5 with Na + and giving evidence of CF…metal cation interaction. Cation binding constants (beta, evaluated by UV titration method), demonstrate that F-A15C5 and F2-A218C6 form more stable complexes than their fluorine-free analogs. The effect depends on the nature of the metal cation and is at a maximum for hard, singly charged cations (up to 3 logbeta units for K+ complex of F2-A218C6). The X-ray structures of complexes [Pb(F2-A218C6)(H 2O)](ClO4)2 (1) and [Ba(F2-A 218C6)(ClO4)2] (2) reveal short Pb-F (2.805 A) and Ba-F (2.965 A) contacts. Complex 2 is centrosymmetric (C i), while complex 1 has C2 symmetry with one-side coordination of o-fluorophenyl groups to Pb2+. This “one-side” coordination mode of Pb2+ is indicative of a partial localization of the Pb2+ lone pair.

This compound is a precursor for the bottom-up synthesis of planar one-dimensional graphene nanoribbons with controlled edge morphology and narrow widths. We discuss the synthetic procedures and characterization using 1H NMR, 13C NMR, IR spectroscopy, and elemental analysis.

From 1,2-difunctionalisation to cyanide-transfer cascades-Pd-catalysed cyanosulfenylation of internal (oligo)alkynes

Internal alkynes substituted by aliphatic or aromatic moieties or by heteroatoms were converted into sulphur-substituted acrylonitrile derivatives. Key is the use of Pd catalysis, which allows the addition of aromatic and aliphatic thiocyanates in an intra- A nd intermolecular manner. Substrates with several alkyne units underwent further carbopalladation steps after the initial thiopalladation step, thus generating in a cascade-like fashion an oligoene unit with sulphur at one terminus and the cyano group at the other.

Synthesis, crystal structure and DNA-binding properties of a nickel(II) complex with 2, 6-bis(2-benzimidazolyl)pyridine

A novel complex of nickel(II) picrate (pic) with the V-shaped ligand 2, 6-bis(2-benzimidazolyl) pyridine (bbp) was synthesized and characterized by elemental analysis, electrical conductivity, and IR and UV/Vis spectral measurements. The crystal structure of the nickel(II) complex ([Ni(bbp) 2](pic)2¡¤2DMF) has been determined by single-crystal X-ray diffraction. The Ni(II) cation is bonded to two bbp ligands through six nitrogen atoms, resulting in a distorted octahedral geometry. The DNA-binding properties of the nickel(II) complex were investigated by electronic absorption and fluorescence spectra and by viscosity measurements. The experimental results suggest that the nickel(II) complex binds to DNA in an intercalation mode.

Non-halogenated solvent-processed ternary-blend solar cells: Via alkyl-side-chain engineering of a non-fullerene acceptor and their application in large-area devices

Solution processability is one of the advantages of organic solar cells (OSCs). However, most high-efficiency OSCs are prepared using hazardous chlorinated solvents for the deposition of photoactive layers. The replacement of non-halogenated solvents with eco-friendly green solvents for photoactive materials is urgently required. Herein, we have developed a novel asymmetric T2-OEHRH, which is modified from the symmetric T2-ORH. The introduction of asymmetric alkyl side chains onto rhodanine end groups can effectively suppress excessive self-aggregation/crystallization and substantially improve solubility without sacrificing optoelectrical properties. Therefore, ternary-blend OSCs based on PTB7-Th:EH-IDTBR:T2-OEHRH processed using a non-halogenated solvent system exhibit a uniform and favorable morphology and give a high power conversion efficiency (PCE) of 12.10%. More importantly, we demonstrate an impressive PCE of 9.32% for large-area NFA-OSCs (substrate size = 100 cm2 and aperture size = 55.5 cm2) prepared via D-bar coating in air. To our knowledge, this PCE is the highest reported to date for NFA-based large-area OSC modules processed from a non-halogenated solvent. This asymmetric alkyl-chain engineering strategy can be exploited to develop high-performance large-area NFA-OSCs with eco-friendly solvent processing.
