A photochemical synthesis of enol ethers and furan-3(2H)-ones from 1,3-dicarbonyl compounds and aryl diazoacetates has been developed. Significantly, 1,4-dioxane promoted O-alkylation of various 1,3-dicarbonyl compounds beyond previous carbene insertion into C–H and C–C bonds has been disclosed.

除卡宾插入 C-H 和 C-C 键外，二恶烷促进 1,3-二羰基化合物的光化学 O-烷基化

已经开发出由1,3-二羰基化合物和重氮乙酸芳基酯光化学合成烯醇醚和呋喃-3(2H ) -酮的方法。值得注意的是，1,4-二恶烷促进了各种1,3-二羰基化合物的O-烷基化，超越了之前卡宾插入C-H和C-C键的作用。
