Reaction of 2-methoxy-N-(1-methylpropylidene)-1-(methylsulfanyl)buta-1,3-dien-1-amine with ButOK resulted in 2-ethylidene-6-methoxy-7-(methylsulfanyl)-3,4,5,6-tetrahy-dro-2H-azepine, the first example of 2-ethylidene-3,4,5,6-tetrahydro-2H-azepines, along with hitherto unknown 7-ethyl-3-methoxy-2-(methylsulfanyl)-4,5-dihydro-3H-azepine and 2-ethyl-6-methoxy-3H-azepine.
2-甲氧基-N-(1-甲基亚丙基)-1-(甲硫基)丁-1,3-二烯-1-胺与ButOK反应生成2-亚乙基-6-甲氧基-7-(甲硫基)-3, 4,5,6-四氢-2H-氮杂卓,2-亚乙基-3,4,5,6-四氢-2H-氮杂卓的第一个例子,以及迄今为止未知的7-乙基-3-甲氧基-2- (甲基硫基)-4,5-二氢-3H-氮杂卓和2-乙基-6-甲氧基-3H-氮杂卓。
