    摘要:
    E-3-azido-3-hexene-2,5-dione (1) 在质子介质中的热分解引起了叠氮化物 1 的几个新反应,包括衍生自烯酮亚胺 11 的加合物。与叔丁基硫醇反应产生两种产物,烯酮亚胺衍生的硫醇加成产物 20 和亚磺亚胺 6 。捕获乙烯基氮烯中间体或硫代-施陶丁格反应被认为是形成亚磺亚胺 6 的可能机制。当在甲醇或叔丁胺中进行热分解时,不存在乙烯基氮烯加成产物 3 和 5 表明硫代-施陶丁格反应有效。

    A versatile process for the preparation of a number of 3-thio-substituted furans 1–4 is described. These products have very low odor thresholds and are thus potent flavor compounds. Fur-3-yl thiocyanates 10a, b as well as other S-containing analogues (2b, 7a, b, and 8) were prepared by a Michael-type addition of thiocyanic acid, thioacetic acid, alakanethiols, and sodium thiosulfate to alkynones 6
