Studies on tetrahydroisoquinolines. XXIX. Reaction of 7-acetoxy-1,2,3,4,6,7-hexahydro-1-(2-(3',4'-dimethoxy- or 3',4'-methylenedioxyphenyl)ethyl)-7-methoxy-2-methyl-6-oxo-isoquinoline (o-quinol acetate) with acetic anhydride in the presence of acid.
摘要:
对1, 2, 3, 4-四氢-1-苯乙基异喹啉-6-醇(6a, b)的o-喹酮乙酸酯(5a, b)进行醋酸酐处理,在酸(浓硫酸、BF3·Et2O或CF3COOH)的存在下,得到了2-乙氧基同阿波啡碱(4a, b)和/或醛-酰胺(7a, b),而产品的比例强烈依赖于所选酸和溶剂。提出了一条机理途径。
