A novel compound is disclosed having the structure ##STR1## in which R is H or lower alkyl, R* is intermediate alkyl, and X is halogen or pseudohalogen. Also disclosed is a method for preparing the compound, the method including the steps of reacting (intermediate alkyl)benzene (I) with succinic anhydride to form (intermediate alkyl)-benzoylpropionic acid (II), successively reducing and dehydrating (II) to form 7-(intermediate alkyl)-1-tetralone (III), alkylating (III) to form 2-hydroxy(lower alkylidene)-7-(intermediate alkyl)-1-tetralone (IV), acrylating (IV) to form 2-acyloxy(lower alkylidene)-7-(intermediate alkyl)-1-tetralone (V), reacting (V) in the presence of an cycloalkene to form 7(intermediate alkyl)-2-(lower alkyl)-1-naphthol (VI), reacting (VI) with a 2,6-dihaloquinone-4-haloimide to form the compound (I), and isolating it.
揭示了一种具有结构##STR1##的新化合物,其中R为H或较低的烷基,R*为中间烷基,X为卤素或伪卤素。还公开了一种制备该化合物的方法,该方法包括以下步骤:将(中间烷基)苯(I)与琥珀酸酐反应以形成(中间烷基)-苯甲酰丙酸(II),依次还原和脱水(II)以形成7-(中间烷基)-1-四氢萘酮(III),烷基化(III)以形成2-羟基(较低烷基亚基)-7-(中间烷基)-1-四氢萘酮(IV),丙烯化(IV)以形成2-酰氧基(较低烷基亚基)-7-(中间烷基)-1-四氢萘酮(V),在环烯烃存在下将(V)与环烯烃反应以形成7-(中间烷基)-2-(较低烷基)-1-萘酚(VI),将(VI)与2,6-二卤喹喔酮-4-卤亚胺反应以形成该化合物(I),并将其分离。
