the design and synthesis of 1-[((hetero)aryl- or piperidinylmethyl)amino]-2-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-2-ols showing various degrees of antifungal activity against Candida albicans and Aspergillus fumigatus strains. Now we have identified a series of 1-[(1H-indol-5-ylmethyl)amino] derivatives which exhibited potent MICs (<65 ng mL−1) against C. albicans strain. The synthesis and SAR behind
我们之前曾报道过1-[((杂)芳基-或哌啶基甲基)氨基] -2-苯基-3-(1 H -1,2,4-三唑-1-基)丙-2-的设计与合成醇对白念珠菌和烟曲霉菌株表现出不同程度的抗真菌活性。现在,我们已经鉴定出一系列1-[((1 H-吲哚-5-基甲基)氨基]衍生物,它们对白色念珠菌菌株具有有效的MIC(<65 ng mL -1)。将讨论吲哚支架背后的合成和SAR。
Electrochemical atom transfer radical addition of polychloroalkanes to olefins promoted by 4,4‐di‐tert‐butyl bipyridine
A new electrochemical strategy for the atom transfer radicaladdition (ATRA) of polychloroalkanes across olefins has been realized by the synergism of paired electrolysis and halogen bonding activation. Notably, readily accessible 4,4-di-tert-butyl bipyridine (dtbpy), acting as a halogen bonding acceptor, shifted the reduction potential of C—Cl bonds positively by 110 mV. The decreased operating potential

Nitrogen Nucleophiles: A general method for direct N-acylation of less nucleophilic nitrogen heterocycles with carboxylic acids is reported. The method, which uses simple, commercially available reagents, no metals and user-friendly conditions, shows excellent functional group tolerance and broad substrate scope for both nitrogen nucleophiles and carboxylic acids.

A copper(11)-catalyzed oxidative cyclization of enamides to oxazoles via vinylic C-H bond functionalization at room temperature is described. Various 2,5-disubstituted oxazoles bearing aryl, vinyl, alkyl, and heteroaryl substituents could be synthesized in moderate to high yields. This reaction protocol is complementary to our previously reported iodine-mediated cyclization of enamides to afford 2,4,5-trisubstituted oxazoles.
