The synthesis of the indoles 7, 15, 16 with a 3-methoxyphenyl group, attached via an α-side chain of 1,2,or 3 CH2 units, is reported. These compounds, after appropriate protection at C(3), were transformed into the N-[(dimethylamino)methyl]indoles 22, 23, and 24, respectively. When treated with AcCl, these N-Mannich bases gave, in two cases, stable N-(chloromethyl)indoles 25 and 26. In the presence
的吲哚的合成7,15,16与3-甲氧基苯基氧基,连接经由的1,2-α-侧链,或3 CH 2个单位记录。这些化合物中,在后C(3)适当的保护,转化入Ñ - [(二甲基氨基)甲基]吲哚22,23,和24,分别。当ACCL处理,这些ñ -曼尼期碱了,在两种情况下,稳定ñ - (氯甲基)吲哚25和26。在SnCl 4的存在下,闭环通过1-亚甲基亚吲哚鎓离子对甲氧基苯基的亲电攻击。的七元环(形成27,28)和八元环(29)被发现是有利的方法。在该系列中未发生环化为六元环的情况。
