The synthesis of 3-allyl-4-ethyl-2- (1'-hydroxyethyl)-1-methoxynaphthalene and its behaviour towards base- and palladium-promoted cyclisation under aerobic and anaerobic conditions

by Swigelaar, Wendell Peter

Over the years, Giles and co-workers have established that, upon treatment with potassium tert-butoxide, tetra-substituted naphthalenes undergo cyclisations to afford naphthopyrans. It was suggested that these base-induced cyclisations was as a result of the reacting centers being forced into close proximity as a consequence of steric crowding.

This thesis describes the synthesis of 3-allyl-4-ethyl-2-(1′
