An investigation into the formation of benzo- and naphtho-pyrans by cyclisation of ortho-alkenyl(hydroxyalkyl)benzenes using either cerium(IV) ammonium nitrate or potassium t-butoxide in dimethylformamide
Abstract
A series of ortho-alkenylbenzyl alcohols carrying methoxy substituents at appropriate positions on the aromatic ring have been synthesised. Each of these compounds has been treated separately with each of the title reagents.
