Synthesis of Benzofurans from Oxygenated Phenoxyamines

Article abstract of DOI:10.1021/jo00197a014

O-Aryloximes having various oxygenated substitution patterns have been converted to benzofurans, with implications toward natural product synthesis, through an extension of the Fischer indole type of synthesis.The effect of the substituent pattern in the benzene ring and the nature of the carbonyl derived portion of the oxime on benzofuranization were explored.
