Chan酰氧基乙酸酯重排反应-有机合成
强碱性条件下，酰氧基乙酸酯经过环氧化物中间体，重排生成2-羟基-3-酮酯的反应。产物可以进一步氧化得到α奶妈疼你,β-二酮酯。
氮杂Chan重排反应可以将2一拳皇者,5-二酮基哌嗪重排缩环。

反应实例
2-Hydroxy-3-keto ester (8). To LDA [(from iPr2NH (24 mmol) and n-BuLi (15 mL of 1.6 M in hexane) in dry THF (50 mL), under N2 at 0 C]笃姬no.1, was added 7 (10 mmol) in THF (10 mL) at -78 C. After 30 min the mixture was quenched with 0.1N HCl, warmed to r.t.米雪冥婚 , worked up and chromatographed to afford 8 (57%).
