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
已经开发了合成取代的萘,菲和其他多核芳烃的有效途径。该方法包括在α-氧杂环丁烯二硫缩醛或β-氧二硫缩醛中加入苄基,1-(萘基甲基)或2-(萘基甲基)卤化镁的1,2-(或顺序的1,4-和1,2-),然后再加入三氟化硼醚化物催化所得甲醇的环芳构化。
