reported. Assisted by boron trifluoride diethyl etherate, the one-pot reaction of aryl homopropargyl alcohols and aldehydes in the presence of arenes yielded indene derivatives. The reaction was studied with various substrates, which suggests a cascade reaction including a sequence of Prins, Friedel–Crafts, ring-opening reactions, and Friedel–Crafts to form three C–C bonds leading to indenes.
报告了一种新的有效的制备茚的方法。在三氟化硼二乙基醚化物的辅助下,芳基高炔丙醇和醛在芳烃存在下的一锅反应产生了茚衍生物。该反应在各种底物上进行了研究,这表明了级联反应,包括一系列的Prins,Friedel-Crafts,开环反应和Friedel-Crafts,形成三个C-C键,从而导致茚基。
