Synthesis of Axially Chiral Anilides Enabled by a Palladium/Ming-Phos-Catalyzed Desymmetric Sonogashira Reaction

Atropisomeric anilides are one of important C—N axially chiral compounds. Compared with the N-terminal functionalization to prepare such compounds, C-terminal functionalization strategies have been rarely reported. We describe herein an efficient synthesis of axially chiral anilides enabled by Pd-catalyzed desymmetric Sonogashira cross-coupling reactions with the use of a newly identified Ming-Phos. Moderate to high yields with high enantioselectivities (up to 98% ee) were obtained.

Solvent-Free and Liquid-Phase Iodination of Thiophene Derivatives with Potassium Dichloroiodate Monohydrate

Iodination of a series of benzene and thiophene derivatives by potassium dichloroiodate monohydrate was studied with and without a solvent. The liquid substrates tend to be more reactive in water while the solid substrates afford better yields in dichloromethane or under the solvent-free conditions. The 2-substituted thiophenes show good to excellent yields whereas the yield for 3-substituted and 3,4- or 2,4-disubstituted thiophenes and benzene derivatives are significantly lower. The mechanochemical reaction of 5-carbaldehyde-2,2′-bithiophene shows excellent yields, while 2,2′-bithiophene gives practical yields only in dichloromethane. In the case of thiophene and N -acetyl- p -toluidine, electrophilic iodination is accompanied by a small extent of chlorination.

NEW COMPOUND

PROBLEM TO BE SOLVED: To provide a new compound that does not have structural similarity to ceramide and has excellent CERT inhibitory activity. SOLUTION: The present invention provides a new compound of structural formula (I). A bond group -X- is cis-cyclopropyl-, R1, R2, R3, R4, and R5 independently represent a hydrogen atom, a halogen atom, a linear or branched C1-C8 alkyl group that may have a halogen atom, or OR6.

One-Pot Synthesis of Pyrrolo[3,2,1-kl]phenothiazines through Copper-Catalyzed Tandem Coupling/Double Cyclization Reaction

A novel and efficient synthesis of pyrrolo[3,2,1-kl]phenothiazines has been developed through a Cu(I)-catalyzed tandem C-S coupling/double cyclization process. Using 2-alkynyl-6-iodoanilines and o-bromobenzenethiols as the starting materials, a wide range

A highly regioselective synthesis of N-acyl-2-acyl(aroyl)indolium Chloride through Palladium-Copper Catalysis Followed by Friedel-Crafts Reaction

2-Trimethylsilylethynyl acetanilides, obtained from the palladium-catalyzed reactions of 2-iodoacetanilides with trimethylsilylacetylene, underwent Friedel-Crafts acylation reactions yielding the N-acyl-2-acyl(aroyl)indolium chlorides in good yields. Georg Thieme Verlag Stuttgart New York.

A mild and convenient synthesis of 1,2,3-triiodoarenes via consecutive iodination/diazotization/iodination strategy

A mild and convenient synthesis of 1,2,3-triiodoarenes has been developed. This method consists of two steps which can be performed on multigram scale with moderate to excellent yields. This report discloses a practical synthesis of 1,2,3-triiodoarenes and 1,2,3-trihaloarenes that is general in scope, operationally simple, scalable, and is easy to workup and to purify. We also report the first regioselective transmetalation reaction of 1,2,3-triiodoarenes to provide ortho-diiodoaryl derivatives, which are useful building blocks and indeed are hard to make by other means.

An all-photonic molecule-based parity generator/checker for error detection in data transmission

The function of a parity generator/checker, which is an essential operation for detecting errors in data transmission, has been realized with multiphotochromic switches by taking advantage of a neuron-like fluorescence response and reversible light-induced transformations between the implicated isomers.

Synthesis and structural insights of substituted 2-iodoacetanilides and 2-iodoanilines

This study reports a simple and efficient method for the direct iodination of substituted anilines with molecular iodine and copper acetate in acetic acid producing 2-iodoacetanilies and 2-iodoanilines. Employing density functional theory (B3LYP) and MidiX basis set, computational study is performed to calculate equilibrium geometries, IR vibrational frequencies, and thermodynamic properties including change of energy, enthalpy and Gibbs free energies. The optimized geometries indicated longer C-I bond distance (2.133 ?) which makes iodine slightly positive. The partial atomic charge profile and electrostatic potential further confirmed that most of the iodinated products are capable of forming a distinct halogen bonding . The thermodynamic properties disclosed that all iodination reactions are endothermic. Understanding the substituents' effect, molecular frontier orbital (MO) calculations are conducted finding the HOMO, LUMO and HOMO-LUMO gaps for all compounds. The MO calculations revealed that two electron-withdrawing iodine groups have significant influence on lowering the HOMO-LUMO gap compared to one iodine group in the products.

Ecofriendly iodination of activated aromatics and coumarins using potassium iodide and ammonium peroxodisulfate

An environmentally benign protocol for the iodination of activated aromatics, such as phenols, anilines, and hydroxycou-marins, using inexpensive commercially available potassium iodide and ammonium peroxodisulfate (1:2.5 molar equivalents per mole of substrate) in aqueous methanol (MeOH-H 2O, 6:1) at room temperature has been developed. The protocol provides for ortho-selective monoiodination as the predominant product without added acid and it is compatible with a number of common oxidizible functional groups, such as formyl, benzylic C-H, aromatic amines and hydroxymethyl. Good to acceptable yields of monoiodinated products in acceptable reaction times and exclusive ortho-iodination for 7-hydroxycoumarins, despite the presence of vinylogous electronrich C3, are some of the key advantageous features of the method.
