Abstract
Eudalene was synthesized from bromobenzene as follows. 3- (p-bromobenzoyl) propionic acid (1) obtained by succinoylation of bromobenzene was converted to 7-bromo-1, 2, 3, 4-tetrahydronaphthalen-1-one (3) through 4- (p-bromophenyl) butyric acid (2). 7-Bromo-1-methyl-3, 4-dihydronaphthalene (5) obtained from (3) was dehydrogenated to give 7-bromo-1-methylnaphthalene (6) with sulfur. Eudalene (7) was obtained by the reaction of Grignard reagent from (6) with acetone, followed by reduction with hydrogen iodide.
