The synthesis of two rotationally restricted phenolic analogs (1a and 1b) of the neurotransmitter serotonin have been accomplished. The syntheses of 8.9-dihydropyrano[3,2-e]indole (13a) and 7,8-dihydropyrano[2,3-f]indole (13b), which formed the template for these targets, are outlined. These novel fused-indoles represent rotationally restricted phenolic analogs of 5-hydroxyindole. The reaction sequence
已经完成了神经递质5-羟色胺的两个受旋转限制的酚类类似物(1a和1b)的合成。概述了形成这些靶标模板的8.9-二氢吡喃并[3,2-e]吲哚(13a)和7,8-二氢吡喃并[2,3-f]吲哚(13b)的合成。这些新颖的熔融吲哚代表5-羟基吲哚的旋转受限的酚类似物。使用克莱森重排,烯烃羟基化和分子内Mitsunobu反应的反应序列形成稠合的二氢吡喃环。
