Benzofuran Derivatives. I. On the Effects of Substituents in Benzofuran Syntheses [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1983
Abstract The Rössing’s reaction of 4-substituted 2-acylphenoxyacetic acids give a mixture of benzofurans and 2-benzofurancarboxylic acids. The relative yields of benzofurans and 2-benzofurancarboxylic acids depend on the substituents on the benzene ring of the 2-acylphenoxyacetic acids.

2,5-Dimethyl-3-phenylsulfinyl-1-benzofuran [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2007
The title compound, C(16)H(14)O(3)S, was prepared by the oxidation of 2,5-dimethyl-3-phenyl-sulfanyl-1-benzofuran with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 76.98 (9)° with the plane of the benzofuran fragment. The crystal structure is stabilized by π-π inter-actions between furan and benzene rings of neighbouring mol ...

Electrooxidation enables highly regioselective dearomative annulation of indole and benzofuran derivatives

open access: yesNature Communications, 2020
Enriching the chemical space of polycyclic heterocycles is of high value in chemical biology. Here, the authors report an electrooxidative protocol for the regioselective dearomative annulation of indoles and benzofurans under undivided cell conditions ...
