Abstract
: An efficient regiocontrolled synthesis of substituted and annulated 1,4-dimethoxynaphthalenes as precursors for 1,4-naphthoquinone systems has been developed through naphthoan-nulation route by regioselective 1,2-addition of 2,5-dimethoxy-benzylmagnesium chloride to acyclic and cyclic a -oxoketene dithioacetals and subsequent BF 3 • OEt 2 assisted cycloaromatiza-tion of the resulting alcohols.
