A one-pot cascade reaction of 1-arylpenta-3,4-dien-2-ones with activated ketones allowed for an efficient and sustainable synthesis of 2-arylphenols. Moreover, this reaction was also found to be compatible and combinable with Pd-catalyzed C-H activation and carbonylation of the in situ formed 2-aryl phenols, thus resulting in a highly convenient and atom-economic synthesis of dibenzopyranones.
1-芳基戊-3,4-二烯-2-酮与活性酮的一锅串联反应实现了2-芳基苯酚的高效可持续合成。此外，该反应还被发现与钯催化的原位生成的2-芳基苯酚的C-H活化和羰基化兼容且可结合，从而实现了二苯并吡喃酮的高度便捷且原子经济的合成。
