Facile Synthesis of 2,3-Diacetoxyflavanones from 3-Aminoflavones
3-Aminoflavone reacts with isopentyl nitrite in acetic acid to give 2,3-diacetoxyflavanone in good yield. 3-Aminoflavone, the starting material, is readily available, and this method is a powerful tool for the synthesis of 2,3-dihydroxyflavanone derivatives.
