Description

Lily aldehyde (also known as lysmeral or Lilial) is a chemical compound commonly used as a perfume in cosmetic preparations and laundry powders1-3. It is fresh light green floral lily muguet lindenblossom aldehyde. Lilial is used in a wide variety of compositions where it confers a particularly recommended for floral notes such as muguet, linden-blossom and cyclamen2.

Chemical Properties

Lily aldehyde is a homolog of cyclamenaldehyde. The racemic compound is a colorless to slightly yellow liquid with a mild-floral odor, reminiscent of cyclamen and lily of the valley.
The aldehyde is prepared by the same routes as cyclamenaldehyde.
Other routes start from ??-methylcinnamaldehyde. ??-Methylcinnamaldehyde (from benzaldehyde and propionaldehyde) is hydrogenated to ??-methyldihydrocinnamic alcohol.The alcohol is alkylated with tert-butyl chloride or isobutene to 4-tert-butyl-??-methyldihydrocinnamic alcohol, which is subsequently dehydrogenated to the desired aldehyde.
4-tert-Butyl-??-methyldihydrocinnamaldehyde is more stable than cyclamenaldehyde and is a popular component of flower compositions, particularly lily of the valley and linden types, because of its mild, pleasant, blossomfragrance. It is used in a wide range of perfume types, but especially in soap and detergent perfumes.
