new strategy for the synthesis of 3-arylisocoumarins and 8-hydroxy-3-arylisocoumarins was investigated by using acyl anion chemistry for the initial C–C bond formation. The obtained keto esters and keto lactones as intermediates underwent based-promoted intramolecular cyclization to afford 3-arylisocoumarins in good yields. The developed methodology was applied for the synthesis of the important natural
3-芳基异香豆素和8-羟基-3-芳基异香豆素的合成新策略通过使用酰基阴离子化学进行初始C-C键形成研究。得到的酮酯和酮内酯作为中间体进行基于促进的分子内环化,以良好的产率得到3-芳基异香豆素。所开发的方法用于合成重要的天然产物 thunberginol A 和 cajanolactone A。
