  摘要：

  基于双靶点抗生素IRS-16的结构，制备了一系列7位取代的1,3-二氨基吡咯[3,2 -f ]喹唑啉化合物。一些衍生物对一组细菌菌株表现出低 MIC。 SAR表明，在分子中引入合适的含氮芳香杂环或亲水胺可以提高其对革兰氏阴性病原体的抗菌活性。

  Intra- and intermolecular thermal transformations of 2-acyl- and 2-alkoxycarbonyl-N-phthalimidoaziridines

  摘要：

  Heating 2-acyl- and 2-alkoxycarbonyl-N-phthalimidoaziridines leads to substituted oxazoles in 45-65% yield. Only esters of oxazolecarboxylic acids are formed when the aziridine contains acyl and alkoxy groups. The thermolysis of the same aziridines in the presence of N-phenylmaleimide and the dimethyl ester of acetylenedicarboxylic acid gives both oxazoles and the products of 1,3-dipolar cycloaddition from aziridines with two substituents at the carbon atoms but only oxazoles from trisubstituted aziridines.

  A silver‐induced cycloaddition of isocyanides with acyl chlorides has been developed. This transition metal‐catalyzed strategy provides an effective and scalable approach for the formation of 2,5‐disubstituted oxazoles in good to high yields. The employed silver‐based MOF catalyst can be efficiently recycled without compromising the yield.

  The potassium salt of triphenylacetic acid is developed as a combined source of CO2 and base/metalating agent. This method avoids specialized equipment and is used in the carboxylation of a range of compound classes. This provides a mechanistically distinct approach to carboxylation that has also been applied in carbon isotope labeling.

  DOI：10.1021/ol101450u

  日期：2010.8.6

  A simple and straightforward method has been developed for the direct carboxylation of aromatic heterocylces such as oxazoles, thiazoles, and oxadiazoles using CO(2) as the C1 source. The reactions require no metal catalyst and only Cs(2)CO(3) as the base. A good functional group tolerance is achieved.
