发展了一种新的乙烯基吲哚与芳炔（由2-（三甲基硅基）芳基三氟甲磺酸酯生成）的高效、通用的Diels-Alder反应。通过[4 + 2]环加成/芳构化反应，得到了各种功能化的苯并[a]咔唑，产率良好。
A new protocol for a highly efficienct and versatile Diels–Alder reaction of vinylindoles with arynes (generated form 2-(trimethylsilyl)aryl triflate) has been developed. Various functionalized benzo[a]carbazoles were afforded in good to perfect yields via [4 + 2] cycloaddition/aromatization.
