开发了AgSbF6催化环状Morita-Baylis-Hillman醇及其类似物与芳基乙烯的顺式[5+2]环加成反应, 同时有效构建了茚酮稠合苯并[7]轮烯骨架化合物. 密度泛函理论(DFT)计算结果表明, 1,3-顺式选择性可能受动力学控制. 二氢二苯并[a,f]薁-12-酮产物3a可以通过区域选择性的氢化和环丙烷化反应进行衍生化.

关键词: Morita-Baylis-Hillman醇, 芳基乙烯, 银催化, [5+2]环加成

An AgSbF6-catalyzed diastereoselective [5+2]-cycloaddition reaction was developed as an efficient entry into indanone-fused benzo[7]annulene frameworks from cyclic Morita-Baylis-Hillman alcohols and its analogues with aryl- ethylenes. Density functional theory (DFT) calculation data analysis shows that 1,3-cis-selectivity might be mainly controlled by kinetics. The resulting dihydrodibenzo[a,f]azulen-12-one 3a can be further functionalized by using the regioselective hydrogenation and cyclopropanation.

Key words: Morita-Baylis-Hillman alcohol, arylethylenes, silver catalysis, [5+2]-cycloaddition
