Description and Uses

α-Isomethylionone has a fine violet and orris-like odor. This substance may be synthesized by condensation of citral with methyl ethyl ketone controlling the ratio between the n- and iso-forms; the methyl pseudo-ionone obtained is then subjected to ring closure, using strong alkali and high temperature (thus favoring the formation of the normal α- and β-methylionones) or with quaternary ammonium base (thus favoring the formation of wo-forms); See also monographs of α- and β-ionone and methyl α-, β-, and γ-ionones.
