Treatment of 2-methyl-6,7-methylenedioxy-3,4-dihydroisoquinolinium perchlorate (7) with diazomethane afforded a mixture of aziridinium salts (8 + 9) which underwent reaction with MeOH to produce the 1,2,4,5-tetrahydro-3H-3-benzazepine (10a) and 1,2,4,5,6-pentahydro-3H-3-benzazocine (11a) derivatives. Similar treatment of 8 + 9 with water gave 10b and 11b. LAH reduction of 8 + 9 gave 12 and 13b. Compound
用
重氮甲烷处理2-甲基-6,7-亚甲基二氧基-
3,4-二氢异喹啉鎓
高氯酸盐(7),得到
叠氮鎓盐的混合物(8 + 9),使其与MeOH反应生成1,2,4,5-四氢3 H -3-苯并pine庚因(10a)和1,2,4,5,6-五氢3 H -3-苯并佐辛(11a)衍
生物。用
水对8 + 9进行类似处理,得到10b和11b。
LAH减少8 + 9得到12和13b。化合物10a转化为13a和二者13A和13B是由一个路线(合成14 → 15 → 16 → 13涉及photocyclization反应作为关键步骤)。
