Abstract

Comparative Claisen rearrangements of 4-hydroxy - (7) and 4-acetoxy-1-allyloxy-5,8-ethano-5,8-dihydro-5-methoxynaphthalene (1) leading after chemoselective methylation to 4-acetoxy-2-allyl-1,5-dimethoxy-naphthalene (9) were investigated. Lewis acid mediated Fries rearrangements of 4-acetoxy-2-allyl-alkoxy-5-ethoxynaphthalenes lead to the formation of a naphtho[1,2 - b]furan in one case only.
