4,5,6-tetrahydro-7-hydroxy-1H-azepino[5,4,3-cd]indoles by simple heating with amines under an oxygen atmosphere. Serotonins also reacted with various aldehydes to provide 3,4,5,6-tetrahydro-7-hydroxy-1H-azepino[5,4,3-cd]indoles rather than beta-carbolines under basic conditions. In these novel reactions, the presence of the 5-hydroxy group on the indole nucleus was suggested to be essential. Possible
发现5-羟色胺通过在氧气气氛下简单地与胺加热而产生3,4,5,6-四氢-7-羟基-1H-氮杂环庚烷[5,4,3-cd]吲哚。在碱性条件下,5-羟色胺还与各种醛反应生成3,4,5,6-四氢-7-羟基-1H-氮杂环庚烷[5,4,3-cd]吲哚而不是β-咔啉。在这些新颖的反应中,吲哚核上5-羟基的存在被认为是必不可少的。讨论了可能的机制。
