Enolization of 2-(2′-pyridyloxy)phenylacetic acid esters with either potassium or sodium hydride induced a Truce–Smiles rearrangement, producing pyridine substituted 2-benzofuranones. Rearrangement of a 2-(4-nitrophenoxy)phenylacetate and a 2-(2′-pyrimidyloxy)phenylacetate produced similar results.
用氢化钾或氢化钠对2-(2'-吡啶氧基)苯基乙酸酯进行烯化会引起Truce-Smiles重排,产生吡啶取代的2-苯并呋喃酮。2-(4-硝基苯氧基)苯乙酸酯和2-(2'-嘧啶基氧基)苯乙酸酯的重排产生相似的结果。
