By implementing a palladium-catalyzed Suzuki coupling reaction ofN-acyloxazolidinones with arylboronic acid, we herein report on the preparation of substituted diaryl ketones via selective cleavage of exocyclic C-N Bonds. The reaction was carried out under mild reaction conditions with excellent functional group compatibility in good yields (up to 93 %).

The chlorination of a bioactive compound can change its physiological properties and improve its pharmacokinetic and pharmacological profiles. It therefore has been an important strategy for drug discovery and development. However, the direct aromatic chlorination of complex bioactive molecules is too difficult to be practical. In fact, many functional groups such as hydroxyls, amines, amides or carboxylic acids may strongly restrain the reactivity of Cl+ by forming a halogen bond. Here we report a highly efficient aromatic chlorination of arenes that is catalysed by dimethyl sulfoxide with N-chlorosuccinimide as the chloro source. The mild conditions, easy-availability and stability of the catalyst and reagents, as well as good functional-group tolerance, showed the approach to be a versatile protocol for the late-stage aromatic chlorination of complex natural products, drugs and peptides. The multi-gram experiment and low-cost of N-chlorosuccinimide and dimethyl sulfoxide shows great potential for drug discovery and development in industrial applications. Late-stage aromatic chlorination of active pharmaceutical ingredients has enormous potential in drug discovery yet still features limited applicability due to issues of functional-group tolerance. Now, dimethyl sulfoxide is reported as catalyst for the chlorination of a diverse family of bioactive molecules in combination with N-chlorosuccinimide.

SDS of cas: 151-10-0. I found the field of Chemistry very interesting. Saw the article Synthesis, Resolution, Configurational Stability, and Properties of Cationic Functionalized [5]Helicenes published in 2020, Reprint Addresses Lacour, J (corresponding author), Univ Geneva, Dept Organ Chem, CH-1211 Geneva 4, Switzerland.; Dimitrov, V (corresponding author), Bulgarian Acad Sci, Ctr Phytochem, Inst Organ Chem, Sofia 1113, Bulgaria.. The CAS is 151-10-0. Through research, I have a further understanding and discovery of 1,3-Dimethoxybenzene.

A straightforward approach to the synthesis of two different series of cationic [5]helicenes has been achieved including, in dioxa series, the possibility to introduce aromatic functional groups at the periphery of the helical structure. While photophysical study highlights that the introduction of aryl substituents at position 23 of the helical moieties has a negligible impact on the optical properties, styryl substituents allow a welcoming extension of the conjugation pathways. Finally, a red shift of the optical properties was evidenced upon introduction of nitrogen atoms in the helicene scaffold, leading to particularly good fluorescence efficiencies in the red domain for a helicenic dye. Detailed information on racemization kinetics was collected for the most stable species upon direct high-performance liquid chromatography (HPLC) resolution or, when configurational lability was too high, through VT-HPLC analysis on the chiral stationary phase (Delta G double dagger values ranging from 85.0 to 137.1 kJ.mol(-1) and above).

We present a computational study of polarizabilities and hyperpolarizabilities of organic molecules in aqueous solutions, focusing on solute-water interactions and the way they affect a molecule’s linear and non-linear electric response properties. We employ a polarizable quantum mechanics/molecular mechanics (QM/MM) computational model that treats the solute at the QM level while the solvent is treated classically using a force field that includes polarizable charges and dipoles, which dynamically respond to the solute’s quantum-mechanical electron density. Quantum confinement effects are also treated by means of a recently implemented method that endows solvent molecules with a parametric electron density, which exerts Pauli repulsion forces upon the solute. By applying the method to a set of aromatic molecules in solution we show that, for both polarizabilities and first hyperpolarizabilities, observed solution values are the result of a delicate balance between electrostatics, hydrogen-bonding, and non-electrostatic solute solvent interactions.

Photochemistry provides a sustainable pathway for organic transformations by inducing radical intermediates from substrates through electron transfer process. However, progress is limited by heterogeneous photocatalysts that are required to be efficient, stable, and inexpensive for long-term operation with easy recyclability and product separation. Here, we report that boron carbonitride (BCN) ceramics are such a system and can reduce organic halides, including (het)aryl and alkyl halides, with visible light irradiation. Cross-coupling of halides to afford new C-H, C-C, and C-S bonds can proceed at ambient reaction conditions. Hydrogen, (het)aryl, and sulfonyl groups were introduced into the arenes and heteroarenes at the designed positions by means of mesolytic C-X (carbon-halogen) bond cleavage in the absence of any metal-based catalysts or ligands. BCN can be used not only for half reactions, like reduction reactions with a sacrificial agent, but also redox reactions through oxidative and reductive interfacial electron transfer. The BCN photocatalyst shows tolerance to different substituents and conserved activity after five recycles. The apparent metal-free system opens new opportunities for a wide range of organic catalysts using light energy and sustainable materials, which are metal-free, inexpensive and stable.

A green, efficient and cheap demethylation reaction of aromatic methyl ethers with mineral acid (HCl or H2SO4) as a catalyst in high temperature pressurized water provided the corresponding aromatic alcohols (phenols, catechols, pyrogallols) in high yield. 4-Propylguaiacol was chosen as a model, given the various applications of the 4-propylcatechol reaction product. This demethylation reaction could be easily scaled and biorenewable 4-propylguaiacol from wood and clove oil could also be applied as a feedstock. Greenness of the developed method versus state-of-the-art demethylation reactions was assessed by performing a quantitative and qualitative Green Metrics analysis. Versatility of the method was shown on a variety of aromatic methyl ethers containing (biorenewable) substrates, yielding up to 99% of the corresponding aromatic alcohols, in most cases just requiring simple extraction as work-up.

The first successful example of deacylative annulation of 1,3-diones with sulfoxonium ylides was achieved through Ru(ii)-catalyzed C-C bond activation. The excellent chemoselectivity and broad substrate scope render this method a practical and versatile approach for the preparation of (hetero)aryl and alkenyl substituted furans, which are valuable units in many biologically active compounds and functional materials. A preliminary mechanistic study reveals that this process involves a deacylative alpha-ruthenation to generate key alkyl Ru(ii) intermediates with the release of a benzoic acid fragment.

We report the preparation of lithium-salt-free KDA (potassium diisopropylamide; 0.6 m in hexane) complexed with TMEDA (N,N,N ‘,N ‘-tetramethylethylenediamine) and its use for the flow-metalation of (hetero)arenes between -78 degrees C and 25 degrees C with reaction times between 0.2 s and 24 s and a combined flow rate of 10 mL min(-1) using a commercial flow setup. The resulting potassium organometallics react instantaneously with various electrophiles, such as ketones, aldehydes, alkyl and allylic halides, disulfides, Weinreb amides, and Me3SiCl, affording functionalized (hetero)arenes in high yields. This flow procedure is successfully extended to the lateral metalation of methyl-substituted arenes and heteroaromatics, resulting in the formation of various benzylic potassium organometallics. A metalation scale-up was possible without further optimization.
