Lily of the Valley Odorant Compound for Stable Fragrance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for novel perfuming ingredients that replicate the complex white floral odor of lily of the valley, as existing compounds like Lilial have limitations and do not survive extraction methods effectively, and current alternatives do not fully capture the natural scent.
Innovation Solution
A compound of formula (I) is developed, which imparts a lily of the valley note with green and ozone aspects, suitable for use in perfumery as a perfuming ingredient, and can be used in perfuming compositions or consumer products to enhance or modify odor properties, provide arthropod control, and exhibit antimicrobial effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Lilial (2-methyl-3-[4-(2-methyl-2-propanyl)phenyl]propanal) is used as a perfuming ingredient, then a lily of the valley and watery connotation is achieved, but its use is limited due to various reasons and it does not survive extraction methods effectively
Solution Approach 1:
The patent creates a structural analog (compound of formula I) that copies the essential lily of the valley odor profile of Lilial while modifying the molecular structure to improve stability. The compound retains the key odor-determining structural features (isopropyl-substituted cycloalkenyl group with aldehyde function) but uses a more stable chemical framework that survives extraction methods.
2Measurement precision
If existing compounds are used to replicate lily of the valley scent, then some floral note is achieved, but they do not fully capture the natural scent and lack the complex white floral odor
Solution Approach 1:
The patent optimizes specific molecular parameters (ring size, substituent positions, alkyl group types) to achieve the precise lily of the valley odor profile. By systematically varying these structural parameters in compound I, the invention achieves superior odor accuracy compared to prior art while maintaining reasonable synthetic accessibility through defined substitution patterns.
3Power
If a compound provides strong top note and bloom effect, then fragrance power is enhanced, but the compound must achieve complex odor properties
Solution Approach 1:
The patent concentrates the odor-active functionality in specific local regions of the molecule (the aldehyde group and isopropyl substituent on the cycloalkenyl ring). This localized functional arrangement allows the compound to achieve strong top note and bloom effects without requiring complex overall molecular structure, as the key odor-determining features are concentrated in specific structural elements of compound I.
