Perfuming Compound Structure for Lactonic and Green Odor Notes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The perfumery industry lacks compounds that impart novel lactonic and green notes, with existing compounds like Veloutone® offering different chemical structures and organoleptic properties.
Innovation Solution
Development of a compound of formula (I) with C10-C16 alkenyl or alkadienyl groups, specifically C12-C13 compounds, which can exist as stereoisomers or mixtures, providing lactonic and green notes, distinct from existing perfuming ingredients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing compounds like Veloutone® are used, then fruity odor notes are provided, but novel lactonic and green notes are lacking
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure parameters of existing compounds. Specifically, it introduces a carbonyl group at position 1 of the cyclopentane ring and varies the alkyl substituents (methyl groups at positions 2,2,5 and a C2-C8 alkenyl group at position 6), which fundamentally changes the odor profile from fruity to lactonic with green notes, thereby providing novel organoleptic properties
2Adaptability or versatility
If compounds with different chemical structures are used, then different organoleptic properties are achieved, but the desired lactonic and green notes are not obtained
Solution Approach 1:
The patent applies local quality by introducing specific functional groups at specific positions on the cyclopentane ring. The carbonyl group at position 1 and the particular arrangement of methyl groups at positions 2,2,5 create localized structural features that are responsible for the lactonic and green odor characteristics, while the C2-C8 alkenyl group at position 6 provides additional molecular diversity
