  One-pot synthesis of 1-substituted-5-alkylselanyl-1 H -tetrazoles from isoselenocyanates: unexpected formation of N -alkyl- N -arylcyanamides and ( Z )- Se -alkyl- N -cyano- N , N′ -diarylisoselenoureas

  摘要：

  1-Substituted-5-alkylsulfanyl-1H-tetrazoles are well known class of organic substances with various applications in medicinal chemistry or photographic industry. Their selenium analogues, 1-substituted-5-alkylselanyl-1H-tetrazoles are, however, much less explored because of the lack of suitable methods for their preparation. In this work we investigated the synthesis of 1-alkyl/aryl-5-alkylselanyl-1H-tetrazoles from synthetically available alkyl/arylisoselenocyanates. One-pot reactions of arylisoseleno cyanates with sodium azide and alkylating agent led to the target 5-alkylselanyl-1-aryl-1H-tetrazoles but also to interesting side products, namely N-alkyl-N-arylcyanamides and (2)-Se-alkyl-N-cyano-N,N'-diarylisoselenoureas. Nevertheless, when alkylisoselenocyanates were utilized as the substrates, the reactions led exclusively to the formation of 1-alkyl-5-alkylselanyl-1H-tetrazoles in good yields. This simple one-pot procedure brings new possibilities for the preparation of variously substituted selenium compounds. It also opens the way to further investigations of selenium isosteres of the widely utilized 5-thiotetrazole moiety in biomedical applications. (C) 2013 Elsevier Ltd. All rights reserved.

  In this work, a new class of highly potent antituberculosis agents, 1-substituted-5-[(3,5-dinitrobenzyl)sulfanyl]-1H-tetrazoles and their oxa and selanyl analogs, is described. The minimal inhibitory concentration (MIC) values reached 1 μM (0.36–0.44 μg/mL) against Mycobacterium tuberculosis CNCTC My 331/88 and 0.25–1 μM against six multidrug-resistant clinically isolated strains of M. tuberculosis

  在这项工作中，描述了一类新型的高效抗结核药，即1-取代的5-[（3,5-二硝基苄基）硫烷基] -1 H-四唑及其氧杂和硒基类似物。最小抑菌浓度（MIC）值达到了1μM（0.36-0.44微克/毫升）对结核分枝杆菌CNCTC我八十八分之三百三十一和0.25-1μM针对六个多药耐药性临床分离菌株的结核分枝杆菌。这些化合物的抗分枝杆菌作用具有高度特异性，因为它们对所研究的所有八种细菌菌株和八种真菌菌株均无效。此外，这些化合物在四种哺乳动物细胞系中均表现出较低的体外毒性（IC 50 > 30μM）。我们还检查了化合物的结构-活性关系，特别是硝基基团的数量和位置，四唑和苄基部分之间的连接基以及四唑本身对抗分枝杆菌活性的影响。在不对分枝杆菌活性产生负面影响的情况下，四唑上取代基R 1的相对较高的变异性可进一步优化毒性，并进一步优化1-取代的5-[（3,5-二硝基苄基）硫烷基]-的ADME性质。 1 H-四唑化合物。
