| 摘要: | Carpacin (1a), an antidepressant in Asiatic folk medicine from the Carpano tree, is achieved in which the longest linear sequence is only four steps in over all yield 67% from commercially available Sesamol. The key transformations in the synthesis are the selective palladium-catalyzed coupling reactions of aryl bromide with Grignard reagents. The first preparation of its geometric isomer (1b) is described. Highlights of the synthesis include Pd-catalyzed coupling, selective hydrogenation, and Wittig reactions. Carpacin was examined as a potential inhibitor of carcinogenesis. |
