AbstractWe have carried out the synthesis and characterization of some hexahydroisoindolyl benzoic acids and their corresponding ethyl esters by a multicomponent reaction (MCR) between aminobenzoic acids or aminobenzoates, maleicanhydride, and isoprene in the absence of catalysts. According to additional experiments, the MCR takes place by sequential formation of N-arylmaleamic acids from the aminobenzoic
摘要我们在不存在催化剂的情况下,通过氨基苯甲酸或氨基苯甲酸酯,马来酸酐和异戊二烯之间的多组分反应(MCR),对一些六氢异吲哚基苯甲酸及其相应的乙酯进行了合成和表征。根据其他实验,MCR是通过依次从氨基苯甲酸或氨基苯甲酸酯和顺丁烯二酸酐,酸和异戊二烯的Diels–Alder加合物,最后是酰亚胺形成N-芳基马来酰胺酸而发生的。加合物的1 H NMR数据(耦合常数)表明,相应的环己烯环的优选构型是顺式-船,由密度泛函理论(DFT)构象分析和相应构象异构体自旋-自旋耦合常数的DFT计算所支持的事实。我们的MCR合成方法在其他加合物的合成中成功进行了测试,其中使用了环戊二烯和其他苯胺。 图形概要

The present study describes the chemical synthesis and pharmacological evaluation of a new series of eleven compounds stereoisomers of imidobenzenesulfonylaziridines in the forced-swimming test (FST) in mice. The pharmacological results of these compounds show that six of them, given intraperitoneally, reduced the immobility time of mice evaluated in the FST, an-antidepressant-like profile of action similar to imipramine, a well-known standard antidepressant drug used for comparison, without compromising the animals' motor performance. The putative antidepressant-like action demonstrated here indicates their viability for the development of new therapeutic options for the treatment of depression. (c) 2006 Published by Elsevier Ltd.
