Description

Clear yellow liquid. 2-Methyl-3-(3,4-methylenedioxyphenyl)propanal is a colorless to slightly yellow liquid, d204 1.159–1.167, n20D 1.531–1.536, with green, floral odor with top notes of ozone and newmown hay. It can be prepared either by condensation of heliotropin with propanal and subsequent partial hydrogenation of the intermediately formed unsaturated aldehyde or by Lewis catalyzed reaction of 1,2-methylenedioxybenzene with methacrolein diacetate followed.
