摘要:

针对Rhuschalcone Ⅰ的结构特征,将其切为2个合成片断:化合物8和化合物10,然后将2个片断连接。 以间苯二酚和对羟基苯甲醛为起始原料,经选择性甲基化、碘代、甲氧甲基化、羟醛缩合、Ullmann反应和脱保护等步骤,完成了Rhuschalcone Ⅰ的合成。 关键中间体与最终产物的化学结构经1H NMR、13C NMR和ESI-MS等表征及分析予以确认。

关键词: RhuschalconeⅠ, Ullmann反应, 全合成, 羟醛缩合

Abstract:

Rhuschalcone Ⅰ was adopted to two synthetic fragments, compound 8 and compound 10, then the two fragments were combined together. Rhuschalcone Ⅰ were first synthesized by selective methylation, iodination, methoxymethylation, aldol condensation, Ullmann reaction, deprotection from m-dihydroxybenzene and p-hydroxybenzaldehyde. The chemical structures of the key intermediate and the final target product were verified by 1H NMR, 13C NMR and ESI-MS.

Key words: RhuschalconeⅠ, Ullmann reaction, Total synthesis, Aldol condensation
