Process for preparation of a benzofuran derivative

An industrially useful process for producing benzofuran derivatives of formula (1) by formylating a compound of formula (2) (where A1 is a protective group), followed by reaction with a compound of formula (4) (where X1 is a halogen atom), then performing a cyclizing reaction and subsequently performing a reaction for hydroxyl group deprotection.

Formation of Diphenyl Ethers from Cyclohexa-2,5-dienones via 4-phenoxy-4-(1-alkoxy)cyclohexa-2,5-dienones as Probable Intermediates

Acid-catalysed reactions of the cyclohexa-2,5-dienones (3) and (14) with phenol afford diphenyl ethers.Quinol ethers are considered to be intermediates in these reactions, with aromatisation of the cyclohexa-2,5-dienone ring by loss of the 4-(1-alkoxy) side-chain as an aldehyde constituting the driving force.
