6-(4′-Aryloxy-phenyl)vinyl-1,2,4-trioxanes: A new series of orally active peroxides effective against multidrug-resistant Plasmodium yoelii in Swiss mice
摘要:
A new series of 6-(4'-aryloxy-phenyl)vinyl-1,2,4-trioxanes 10a-d, 11a-d, and 12a-d have been synthesized and evaluated for their antimalarial activity against multidrug-resistant Plasmodium yoelii in Swiss mice by oral route. Trioxanes 10b and 10c, the two most active compounds of the series, provided 100% protection to the infected mice at 48 mg/kg x 4 days. Clinically useful drug beta-arteether provided 100% and 20% protection at 48 mg/kg x 4 days and 24 mg/kg x 4 days, respectively, in this model. (C) 2010 Elsevier Ltd. All rights reserved.

We have introduced a novel, efficient, commercially available and economically attractive N-donor tripod ligand, tris-(2-aminoethyl)amine for copper-catalyzed Ullmann diaryl ether synthesis. This catalyst system is highly active for both aryl iodides and aryl bromides. Variously substituted diaryl ethers have been synthesized in good to excellent yields.
2-Carbomethoxy-3-hydroxyquinoxaline-di-N-oxide was identified as an efficient novel ligand for the copper-catalyzedcoupling of arylhalides with various phenols under mild conditions. The catalytic system shows great functional-group tolerance and excellent reactive selectivity.

A hydrogen-transfer strategy for the catalytic functionalization of benzylic alcohols via electronic arene activation, accessing a diverse range of bespoke diaryl ethers and aryl amines in excellent isolated yields (38 examples, 70% average yield), is reported. Taking advantage of the hydrogen-transfer approach, the oxidation level of the functionalized products can be selected by judicious choice
