Uses
Uses in perfumery :
Lyral® is used in floral notes such as white flowers, lily of the valley, lilac or lily.
Year of discovery :
Discovered in 1958. Patent N°868,850 published on May 8, 1958 by IFF
Natural availability :
Lyral® is not available in its natural state.
Isomerism :
The positional isomer that is formed during the synthesis of Lyral® has no great olfactory difference with Lyral® used in perfumery. Geranyl Propionate is a constitutional isomer of Lyral®. Their smell is very different as Geranyl Propionate is much rosier.
Synthesis precursor :
Lyral® forms Schiff bases in the presence of amino compounds such as Methyl Anthranilate or Indole.
Synthesis route :
Lyral® is synthesized by a Diels-Alder reaction between Myrcenol and Acrolein (or Propenal) in the presence of a Lewis catalyst such as zinc chloride. When this reaction is performed without a catalyst and at a high temperature, it results in the formation of a mixture of two positional isomers of Lyral®, although Lyral® is still predominant (70%).
