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。
cis-Selective[5+2]-Cycloaddition Reactions of Cyclic Morita-Baylis-Hillman Alcohols and Its Analogues with Arylethylenes Catalyzed byAg(l)
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.
