Abstract

NEW MATERIAL:A compound I (A is O, hydroxyimino).
EXAMPLE: 4-(3', 4'-Dichlorocinnamoyl)tropolone.
USE: Intermediate of carcinostatic agent.
PROCESS: The objective compound I wherein A is O, is prepared by reacting the compound II (1 mole) with 4-acetyltropolone III (1-3 moles) in an alcohol such as methanol, while adding alkali hydroxide such as NaOH (5-10 moles per 1 mole of the compound III; concentration of the NaOH is ≥ 20%) dropwise, at -10-+ 10°C. The compound can be converted to the compound I wherein A is hydroxyimino, by adding 1-20 moles of hydroxylamine hydrochloride to 1 mole of the compound (A is O), and refluxing by heating at a refluxing temperature of the alcohol used as solvent
