  2-Aryl-3H-indol-3-ones: Synthesis, electrochemical behaviour and antiplasmodial activities

  摘要：

  The synthesis of indolone derivatives and their antiplasmodial activity in vitro against Plasmodium falciparum at the blood stage are described. The 2-aryl-3H-indol-3-ones were synthesized via deoxygenation of indolone-N-oxides. Electrochemical behaviour, antiplasmodial activity and cytotoxicity on human tumor cell lines were compared to those of indolone-N-oxides. The antiplasmodial IC50 (concentrations at 50% inhibition) of these compounds ranged between 49 and 1327 nM. Among them, the 2(4-dimethylaminophenyl)-5-methoxy-indol-3-one, 7, had the best antiplasmodial activity in vitro (IC50 = 49 nM; FcB1 strain) and selectivity index (SI (CC50 MCF7/IC50 FcB1) = 423.4). Thus, the hits identified in this deoxygenated series correspond to their structural homologs in the N-oxide series with comparable electrochemical behaviour at the nitrogen-carbon double bond.

  first example of transition-metal-catalyzed C–H activations of 2-phenylisatogens with alkynes and sulfonyl azides has been developed using N-oxide as the directing group. Ru(II)-Catalyzed C–H alkenylation/cyclization and Ir(III)-catalyzed direct C–H sulfamidation proceeded with good yields and excellent functional group tolerance. Importantly, these two transformations provided straightforward routes

  nitro–alkyne cycloisomerization leading to isatogens. Since the first documentation of this reaction by Baeyer (picture of Baeyer and the corresponding literature citation are shown) in the late 19th century, a mild and general method for the synthesis of isatogens has been sought. The electrophilic PdII halide complexes are found to bring about this cyclization to provide the desired isatogens and accommodate

  properties and development of a general method to construct these derivatives has now been developed. Indolines (2,3-dihydroindoles) and isatogens have been prepared in an efficient route starting from indoles substituted in position 2. Reduction of the 2-substituted indoles was performed with tin and hydrochloric acid to give racemic indolines, which were converted to isatogens by 3-chloroperoxybenzoic
