Herein, a method for the isomerization of the double bonds in tetrahydroxanthones is reported. Tetrahydroxanthones are readily available from salicylaldehydes and cycloalkenones and undergo isomerization upon treatment with AlCl3. The mechanism of the isomerization and follow-up chemistry of the products were investigated. Follow-up chemistry such as asymmetric Corey–Bakshi–Shibata (CBS) reduction
本文报道了一种四氢氧杂蒽酮双键异构化的方法。四氢氧杂蒽酮很容易从水杨醛和环烯酮中获得,并在用 AlCl3 处理后发生异构化。研究了产物的异构化机理和后续化学反应。后续化学反应如不对称 Corey-Bakshi-Shibata (CBS) 还原提供了高度官能化的四氢氧杂蒽酮。
