A New Synthetic Pathway to Symmetric Bisubstituted Naphthoquinones
Migulin, Vasily A.
, p. 60 - 68 (2019/12/26)
straightforward and practical synthesis of 2,3-diiodo-1,4-naphthoquinone is reported. Based on the prepared diiodide, a new synthetic approach to symmetric bisubstituted 1,4-naphthoquinones via double Suzuki-Miyaura reaction at room temperature has been researched and developed. The presented general method combines broad-spectrum applicability, efficiency, and simplicity providing target materials in good to quantitative yields.
Palladium-Catalysed Cross Coupling of Arylboronic Acids with 2-Chloro-1,4-naphthoquinones: The Synthesis of 2-Aryl- and 2,3-Bisaryl-1,4-naphthoquinones

2-Chloro-1,4-naphthoquinones underwent palladium-catalysed cross coupling reactions with arylboronic acids to give the corresponding 2-aryl-1,4-naphthoquinones. Similarly, 2,3-dichloro-1,4-naphthoquinone underwent efficient cross coupling reactions with arylboronic acids to give mono or bis adducts. The required 2-chloro-1,4-naphthoquinones were conveniently prepared from the corresponding 2-hydroxy-1,4-naphthoquinones by treatment with oxalyl chloride.
