Abstract
4-Methoxybenzyl- (A), 3,4-dimethoxybenzyl- (B) and 3,4-methylenedioxybenzyl- (C) Grignard reagents are shown to undergo regioselective 1,2-addition with various acyclic and cyclic -oxoketene dithioacetals to afford carbinol dithioacetals which on BF3.Et2O catalyzed cyclization yield alkoxynaphthalenes and their condensed derivatives in a highly regiocontrolled manner.
