1-substituted indolizines with activity against Mycobacterium tuberculosis have been synthesized. The most active compounds carry an hydroxyphenylmethyl- or hydroxyalkyl substituent in the indolizine 1-position. The alkyl chain should be moderately long (C-5 or C-6). Aryl groups in the 2- and 3-position of the indolizine are also required. Removal of the 3-substituent resulted in significant loss of
A unique strategy toward the synthesis of polysubstituted indolizines has been developed. When 2-pyridinyl-2-(2′-bromoallyl)-1-carboxylates were treated with Cs2CO3, the starting material went through a methylenecyclopropane ring formation/opening cascade, and the corresponding indolizines were obtained in moderate to good yield as a single regioisomer.
已经开发了合成多取代的吲哚嗪的独特策略。当用Cs 2 CO 3处理2-吡啶基-2-(2'-溴烯丙基)-1-羧酸盐时,起始原料经过亚甲基环丙烷成环/开环级联反应,得到相应的吲哚嗪类化合物,收率中等至良好。一个单一的区域异构体。
