Efficient monoacylation of symmetrical secondary alkanediamines and synthesis of unsymmetrical diacylated alkanediamines. A new L-proline-based organocatalyst

A simple procedure was developed for the monoacylation of several unprotected alkanediamines with carboxylic acids by using PyBOP-HOBt as coupling agent in the presence of DIEA at room temperature. Yields were moderate with primary alkanediamines and good to excellent with linear or cyclic secondary ones. To illustrate the utility of these monoacylated products, six unsymmetrical diacylated alkanediamines were synthesized. In addition, one of these compounds was evaluated as organocatalyst in an asymmetric aldol reaction.

PhSO2SCF2H: A Shelf-Stable, Easily Scalable Reagent for Radical Difluoromethylthiolation

A new shelf-stable and easily scalable difluoromethylthiolating reagent S-(difluoromethyl) benzenesulfonothioate (PhSO2SCF2H) was developed. PhSO2SCF2H is a powerful reagent for radical difluoromethylthiolation of aryl and alkyl boronic acids, decarboxylative difluoromethylthiolation of aliphatic acids, and a phenylsulfonyl-difluoromethylthio difunctionalization of alkenes under mild reaction conditions.

General rhodium-catalyzed oxidative cross-coupling reactions between anilines: Synthesis of unsymmetrical 2,2?-diaminobiaryls

Described herein is a dual chelation-assisted RhCl3-catalyzed oxidative C-H/C-H cross-coupling reaction of aniline derivatives. The highlight of this methodology is the chemo- and regioselective cross-coupling between electronically similar substrates, which represents a highly challenging task in oxidative Ar-H/Ar-H cross-coupling reactions. Furthermore, this Cp?-free catalytic reaction tolerates a range of functional groups and requires only a low molar ratio of coupling partners. These features expedite the synthesis of unsymmetrical 2,2?-diaminobiaryls.

Ruthenium-Catalyzed Site-Selective Trifluoromethylations and (Per)Fluoroalkylations of Anilines and Indoles

Introducing (per)fluoroalkyl groups into arenes continues to be an interesting, but challenging area in organofluorine chemistry. We herein report an ortho-selective C?H perfluoroalkylation including trifluoromethylations of anilines and indoles without the need of protecting groups using RfI and RfBr as commercially available reagents. The availability and price of the starting materials and the inherent selectivity make this novel methodology attractive for the synthesis of diverse (per)fluoroalkylated building blocks, for example, for bioactive compounds and materials.

Structural studies and characterization of 3-formylchromone and products of its reactions with chosen primary aromatic amines

The crystal structure and FTIR spectrum of 3-formylchromone (0) have been analysed. A new organic ligands, 3-(anilinomethylene)-2-methoxychroman-4-one (1) and 3-(1?,4?-benzodioxan-6?-aminomethylene)-2-methoxychroman- 4-one (2) were synthesized. The products of reactions between 3-formylchromone and aniline and 6-amino-1,4,-benzodioxane were studied by elemental analysis, FTIR spectroscopy, thermal analysis and X-ray crystallography. It has been found that these reactions allow to obtain derivatives of 4-chromanones from 3-formylchromone by the mechanism of nucleophilic addition, accompanied by the opening of the pyrone ring. The experimental results indicate that compounds (1) and (2) are thermal stable up to 90 and 100 C, respectively. The FTIR spectra and X-ray analysis showed the present of methoxy-group in these compounds.
