ChemInform Abstract: Facile Synthesis of 2,3‐Dihydrobenzofuran‐3‐ylacetic Acids by Novel Electrochemical Sequential Aryl Radical Cyclization—Carboxylation of 2‐Allyloxybromobenzenes Using Methyl 4‐tert‐Butylbenzoate as an Electron‐Transfer Mediator.

Abstract

Besides benzofurans, other cyclic systems can also be constructed. In all cases, trace amounts of open-chain acids of type (IV) are formed. -(SENBOKU*, H.; MICHINISHI, J.-Y.; HARA, S.; Synlett 2011, 11, 1567-1572, http://dx.doi.org/10.1055/s-0030-1260794 ; Div.
