Transition-metal-free Diels–Alder and tandem Diels–Alder/oxidation–aromatization reactions of 2-styrylchromones with arynes have been demonstrated under mild reaction conditions with a wide range of substrates. The tandem process afforded functionalized benzo[c]xanthone derivatives in moderate to good yields. This efficient protocol allows rapid access to either dihydrobenzo[c]xanthone and benzo[c]xanthone derivatives
已证明2-苯乙烯基色酮与芳烃的无过渡金属的Diels-Alder和串联Diels-Alder /氧化-芳香化反应在温和的反应条件下与多种底物一起进行。串联过程以中等至良好的产率提供了官能化的苯并[ c ]]吨酮衍生物。通过简单地改变反应气氛,该有效方案允许快速选择性地快速接近二氢苯并[ c ]黄酮和苯并[ c ]黄酮衍生物。
