α-Oxoketendithioacetals derived from acyclic and cyclic ketones are shown to react with benzylmagnesium chloride to give novel naphthoannelated aromatic compounds by sequential 1,4- and 1,2-additions followed by subsequent cycloaromatization of the resulting carbinols.

An efficient route for the synthesis of substituted naphthalenes, phenanthrenes and other polynuclear aromatic hydrocarbons has been developed. The methodology involves 1,2- (or sequential 1,4- and 1,2-) addition of either benzyl, 1-(naphthylmethyl) or 2-(naphthylmethyl) magnesium halides to α-oxoketene dithioacetals or β-oxodithioacetals followed by borontrifluoride etherate catalyzed cycloaromatization of the resulting carbinols.
