摘要

我们报道了一种通用而简洁的方法，通过铜/光氧化还原双催化烯酸与NHPI酯的碳内酯化，模块化合成各种3,3-二烷基取代的异铬-1,4-二酮。从天然产物和市场上销售的药物中提取的各种NHPI酯都能成功地与该反应相容。用这种方法，可以合成羰基α-位置有季碳中心的各种烷基取代等色罗曼-1,4-二酮，收率很高。

Synthesis of 3,3-dialkyl-substituted isochroman-1,4-diones via copper/photoredox dual-catalyzed carbolactonization of alkenes

We report a general and concise method for modular synthesis of various 3,3-dialkyl-substituted isochroman-1,4-diones via copper/photoredox dual-catalyzed carbolactonization of alkenoic acids with NHPI esters. A diverse range of NHPI esters derived from natural products and marketed drugs are successfully compatible with this reaction. With this approach, various alkyl-substituted isochroman-1,4-diones featuring a quaternary carbon center at the α-position of the carbonyl group can be synthesized in good to excellent yields.
