A facile visible light promoted approach to anthracenone-furans from readily available 2,3-dibromonaphthoquinones and phenylbenzofurans a formal Diels Alder reaction is reported. This reaction involves wavelength-selective agitation of 4CzIPN, energy transfer to quinones, recombination of 1,6-biradicals and elimination to give anthracenone-furans in good to excellent yields in one pot.
报道了一种从易得的2,3-二溴萘醌和苯基苯并呋喃通过简便的可见光促进方法合成蒽醌-呋喃的方法——一种形式上的狄尔斯-阿尔德反应。该反应涉及4CzIPN的波长选择性激发、向醌的能量转移、1,6-双自由基的重组以及消除反应,从而在一锅反应中以良好至优异的产率得到蒽醌-呋喃。
