通过过渡金属催化或 S N Ar 反应制备S -芳基黄原酸酯因其在所用条件下的进一步转化而变得复杂。相比之下,O-烷基黄原酸钾与二芳基碘盐的 S-芳基化反应在温和条件下进行,从而能够获得取代的S-芳基黄原酸。该方法表现出良好的官能团耐受性,可应用于药物分子的后期C-H功能化。由此产生的S -芳基黄原酸酯的不同转化提供了快速获得一系列与药物化学相关的有机硫化合物的途径。
The Cu-catalyzed regioselective synthesis of phenazine N-oxides was realized from benzoxadiazoles and diaryliodonium salts. The process was initiated by the electrophilic arylation of benzoxadiazoles with diaryliodonium salts and followed by benzocyclization reactions. The further reduction of N-oxides in situ to phenazine scaffolds and deviation to organic fluorescent materials were readily accomplished
Diverse Tandem Cyclization Reactions of <i>o</i>-Cyanoanilines and Diaryliodonium Salts with Copper Catalyst for the Construction of Quinazolinimine and Acridine Scaffolds
Two cyclization modes are realized to produce different nitrogen-containing heterocycles, i.e., quinazolin-4(3H)-imines and acridines by assembling o-cyanoanilines and diaryliodonium salts via tandem reaction pathways.
A metal-free direct α-selectivearylation of BODIPYs has been developed based on base-mediated C–Hfunctionalization with easily accessible diaryliodonium salts, which provides a straightforward facile access to a variety of α-arylBODIPY dyes. The α-regioselectivity was confirmed by X-ray analysis, and was studied by DFT calculation. The resultant dyes show strong absorption and emission over a broad
A novel copper-catalyzedtandem C–S/C–C bond-forming reaction of 2-biaryl isothiocyanates with diaryliodonium salts was developed. This is the first general approach to synthesize phenanthridines from 2-biaryl isothiocyanates. This methodology has been successfully applied to the synthesis of trisphaeridine.
secondary thioamides with diaryliodonium salts under basic, transition metal-free conditions resulted in chemoselective S-arylation to provide aryl thioimidates in good to excellent yields. Equimolar amounts of thioamide, base and diaryliodonium salt were sufficient to obtain a diverse selection of products within short reaction times. Reactions with thiolactams delivered N-arylated thioamides in good
