Abstract
3-Acetyltropolone (1) was synthesized from 3-isopropenyltropolone by treatment with sodium azide in concentrated sulfuric acid. Methylation of 1 by diazomethane gave two isomers, 3-acetyl-2-methoxytropone (2a) and 2-acetyl-7-methoxytropone (2b). 1, 2a, and 2b reacted with hydrazine to give some 1,8-dihydrocycloheptapyrazol-8-one derivatives.
