A new strategy of acid-catalysed reactions of indole methanols with a 3-aryl-4,6-dimethoxyindole-7-aldehyde leads to an efficient synthesis of a calix[3]indole with 2,2; 7,2; 7,7-links. A new calix[4]indole containing four indole units with 2,2; 7,2; 7,7; 2,7-links has also been prepared by this strategy.
吲哚甲醇与3-芳基-4,6-二甲氧基吲哚-7-醛酸催化反应的新策略导致杯[3]吲哚与2,2的有效合成;7,2; 7,7-链接。一个新的杯[4]吲哚,含有四个吲哚单元,2,2;7,2; 7,7; 2,7-links 也由这个策略准备。
