A facile approach starting from 2-alkynylarylketones was developed for the construction of functionalized indenones under metal-free and water-assisted conditions.
从2-炔基芳基酮出发,开发了一种简便的方法,在无金属和水辅助条件下构建官能化的茚酮。
Electrochemical Reductive Acylation of 2,3-Disubstituted 1-lndenones
The electrochemicalreductiveacylation of 2,3-disubstituted 1-indenones in the presence of acetic anhydride in aprotic media such as DMF, DMSO, and aceto-nitrile gave 2,3-disubstituted 1-acetoxy-1H-indenes (2) and 1,2-disubstituted 3-acetoxy-1H-indenes (3) in good yields. The ratios of 2 to 3 in the products were affected by the substituents.
