2(1H)-Naphthalenone,3,4-dihydro-6,7-dimethoxy- (2472-13-1)

The systematic name of 6,7-dimethoxy-3,4-dihydronaphthalen-2(1H)-one is 6,7-Dimethoxy-2-tetralone . With the CAS registry number 2472-13-1, it is also named as 2(1H)-naphthalenone, 3,4-dihydro-6,7-dimethoxy- ; 6,7-Dimethoxy-3,4-dihydro-2(1H)-naphthalenone ; 6,7-Dimethoxy-3,4-dihydro-1H-naphthalen-2-one . 

The 6,7-Dimethoxy-2-tetralone can be obtained by many meyhods. For example: 1. it can be prepared by 3-(4,5-dimethoxy-2-methoxycarbonylmethyl-phenyl)-propionic acid methyl ester with KO-tert-Bu , LiCl , HCl and H₂O. The solvent are diethyl ether and dimethylsulfoxide . The reaction type contains condensation, dieckmann reaction, hydrolysis and decarboxylation.

2. The 6,7-Dimethoxy-2-tetralone can be prepared by 5,6-dimethoxy-2,3-dihydro-1aH-1-oxa-cyclopropa[a]naphthalene-7b-carboxylic acid amide .

The 6,7-Dimethoxy-2-tetralone can be used in organic synthesis. It can used to synthesize other chemicals. For example: it can reacts with trifluoro-methanesulfonic acid anilide to get trifluoro-methanesulfonic acid 6,7-dimethoxy-3,4-dihydro-naphthalen- ; it reacts with hydrocyanic acid; potassium salt to get 6',7'-dimethoxy-3',4'-dihydro-1'H-spiro[imidazolidine-4,2'-naphthalene]-2,5-dione ; it reacts with propylamine and methyl 2-(bromomethyl)acrylate to get methyl 4-n-propyl-8,9-dimethoxy-1,2,3,4,5,6-hexahydrobenzo[f]quinoline-2-carboxylate .
