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 by saponification of the corresponding enol acetate . The title compound can be used in perfumes for toiletries, for example, shaving creams and detergents.
