Synthesis of novel 3-alkylbenzofurans via a Wittig olefination and Claisen rearrangement sequence

Article abstract of DOI:10.1055/s-1997-1362

A short and novel synthesis of hitherto unknown 3-alkylbenzofurans is described. Wittig olefination of protected 2-hydroxybenzaldehydes followed by Claisen rearrangement resulted in the formation of pent-4-en-1-als. These, on deprotection and dehydration,
