A palladium-catalyzed [4+4] cycloaddition of aryl-substituted γ-methylidene-δ-valerolactones (GMDVs) with divinylketones (DVKs) was developed, providing an approach to access various mono-cyclic tetrahydro-2H-oxocines with diverse substituents in 41% to 95% yield with 81:19 to >20:1 dr. This reaction was facilitated by anchoring olefin (C=C), carbonyl (C=O), and arene (Ar) at the α-position of carbonyls
开发了芳基取代的 γ-甲基-δ-戊内酯 (GMDV) 与二乙烯基酮 (DVK) 的钯催化 [4+4] 环加成反应,提供了一种获得具有不同取代基的各种单环四氢-2H-氧代辛的方法,收率为 41% 至 95%,产量为 81:19 至 >20:1 dr。通过将烯烃 (C=C)、羰基 (C=O) 和芳烃 (Ar) 锚定在羰基α位置来促进该反应。
