Phenol and aniline oxidative coupling with alkenes by using hypervalent iodine dimer for the rapid access to dihydrobenzofurans and indolines
A highly reactive hypervalent iodine dimer, [Ph(CF3COO)I]-O- [I(OCOCF3)Ph], is utilized as successful promoter in the oxidative phenolic coupling with styrenes leading to 2-aryldihydrobenzofurans. The extensions of the substrates in this study have led to the development of a new expeditious construction of the pyrroloindoline structure from aniline and enamide derivatives.
Mechanistic Aspects and Synthetic Applications of the Electrochemical and Iodobenzene Bis(trifluoroacetate) Oxidative 1,3-Cycloadditions of Phenols and Electron-Rich Styrene Derivatives
Anodic oxidation of p-methoxy-substituted phenols and electron-rich styrene or propenylbenzene derivatives affords in good yield trans-dihydrobenzofurans derived from a formal 1,3-oxidative cycloaddition of the phenol to the styrene derivative.The yield o
