摘要

Earlier studies from this laboratory [1] and by others [2] described the synthesis of substituted indoles from 2-nitrobenzyl ketones based on a tandem reduction—cycloaromatization reaction. Our recent work has sought to assemble more complex structures using this strategy. In this study, we have developed a route to synthesize 1, 2, 3, 9-tetrahydro-4H- carbazol-4-one and 8, 9-dihydropyrido [1, 2-a] indol-6 (7H)-one from 1H-indole-2-butanoic ...
