Synthesis and antitubercular activity of phenothiazines with reduced binding to dopamine and serotonin receptors
摘要:
Analogs of the psychotropic phenothiazines were synthesized and examined as antitubercular agents against Mycobacterium tuberculosis H37Rv. The compounds were subsequently counter-screened for binding to the dopaminergic-receptor subtypes D1, D2, D3 and the serotonergic-receptor subtypes 5-HT1A, 5-HT2A, and 5-HT2C. The most active compounds showed MICs from 2 to 4 mu g/mL and had overall reduced binding to the dopamine and serotonin receptors compared to chlorpromazine and trifluoperazine.

Palladium-Catalyzed Direct Synthesis of Carbazoles via One-Pot N-Arylation and Oxidative Biaryl Coupling: Synthesis and Mechanistic Study
摘要:
An efficient catalytic system has been developed for the synthesis of carbazoles by one-pot N-arylation and oxidative biaryl coupling. A significant substituent effect of the diarylamine intermediate on oxidative Coupling was observed. Mechanistic studies of oxidative coupling, including trapping of reaction intermediates and kinetic isotope effect experiments, are also presented.

A novel I2-catalyzed cross-dehydrogenative aromatization of cyclohexanones and anilines to synthesize N,N′-diaryl-o-phenylenediamines has been unprecedentedly developed with dimethyl sulfoxide and oxygen employed as mild terminal oxidants. To prove the rationality of the two separate dehydration steps of the proposed mechanism, a resulting I2-catalyzed cross-dehydrogenative aromatization of cyclohexenones

Room‐temperature sub‐mol % Ullmann amination has been realized, promoted by the organic ionic base TBPM (14 examples). In addition, the stability and application of ammonium and phosphonium based organic ionic bases at higher temperatures was investigated, leading to a new protocol for the activation of structurally complex amines.

reported. This 'Chan-Evans-Lam' reaction has revealed that at room temperature, catalytic copper(II) acetate and cericammoniumnitrate (CAN) as an oxidant, N-arylation can result in an effective C-N bond formation. This air stable, practical, robust protocol enables a variety of functional group tolerance on both boronic acid and amine partners.
