Photoinduced electron transfer (PET) promoted decarboxylation of α-(ω-carboxyalkyl) β-keto esters undergoes radical ring expansion and cyclization reactions. This mild and environmentally friendly method can provide one-carbon expanded γ-keto esters and bicyclic alcohols, and the product distribution is strongly dependent on the length of the alkyl chain containing the terminal carboxylate group.
光诱导电子转移(PET)促进的α-(ω-羧烷基)β-酮酯的脱羧反应经历自由基环扩张和环化反应。这种温和且环保的方法可以提供一碳扩展的γ-酮酯和双环醇,产物分布强烈依赖于含末端羧酸盐基团的烷基链的长度。
