An efficient rhodium-catalyzed dearomative rearrangement of 2-oxypyridines with quinone diazides has been developed for the direct synthesis of -arylated pyridones, in which a novel 1,6--to- rather than 1,4--to- acyl rearrangement has been achieved under mild reaction conditions.
发展了一种高效的铑催化 2-氧代吡啶与重氮二羧酸酯的去芳构化重排反应，用于直接合成芳基化的吡啶酮，在温和的反应条件下，实现了新颖的 1,6- 而非 1,4-酰基重排。
