A facile iron-catalyzed decarboxylative radical coupling of alkyl diacyl peroxides with coumarins or chromones has been developed, affording a highly efficient approach to synthesize a variety of α-alkylated coumarins and β-alkylated chromones. The reaction proceeded smoothly without adding any ligand or additive and provided the corresponding products containing a wide scope of functional groups in
已经开发了一种简便的铁催化的烷基二酰基过氧化物与香豆素或色酮的脱羧自由基偶联,为合成各种 α-烷基化香豆素和 β-烷基化色酮提供了一种高效的方法。该反应在不添加任何配体或添加剂的情况下顺利进行,并以中等至优异的产率提供了含有广泛官能团的相应产物。该协议的突出特点是其高区域选择性、易于获得的起始材料和操作简单。
