A route to β-substitutedcyclohex-2-enones, 4-arylcoumarins, and biaryls has been developed. This approach involves a one-pot Cu0/Selectfluor-catalyzed dehydration–oxidation of tertiary cycloalcohols. Thus, by using 2 equiv. of Selectfluor at 25 °C, the dehydration–oxidation of tertiary cyclohexanols and oxabenzocyclohexanols gave β-substitutedcyclohex-2-enones and 4-arylcoumarins, respectively; whereas

An umpoled electrophilic 1,4-addition to enones was achieved under photocatalytic conditions. Various enones reacted with CO2 in the presence of an iridium photocatalyst and a benzimidazoline reductant under blue-light irradiation to give the corresponding γ-keto carboxylic acids. Aldehydes also coupled with enones under similar photocatalytic conditions to afford γ-keto alcohols (homoaldols) that
在光催化条件下实现了烯酮的未极化亲电 1,4-加成。各种烯酮在铱光催化剂和苯并咪唑啉还原剂存在下在蓝光照射下与CO 2反应生成相应的γ-酮基羧酸。醛还在类似的光催化条件下与烯酮偶联,得到γ-酮醇(高醛醇),通过共沸后处理将其转化为二氢呋喃和四氢呋喃。D 2 O 在 β 位的区域选择性氘掺入表明 1,4-加成是通过高烯醇阴离子发生的。
