Odorant Compound for Novel Lactonic and Green 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 C2-8 alkenyl or C4-8 alkadienyl group stereoisomers, which provide lactonic and green notes, suitable for use in perfuming ingredients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing compounds like Veloutone® are used, then perfuming ingredients are available, but they do not provide novel lactonic and green notes
Solution Approach 1:
The patent modifies the chemical structure by changing the alkyl group parameters (introducing C2-8 alkenyl or C4-8 alkadienyl groups at specific positions) to transform existing cyclopentanone compounds into novel compounds with lactonic and green scent profiles, thereby resolving the contradiction between having available perfuming ingredients and achieving novel organoleptic properties
2Quantity of substance
If compounds with stronger aromatic notes are developed, then odor intensity is improved, but the chemical structure becomes more complex
Solution Approach 1:
The patent applies local quality by introducing specific functional groups (alkenyl or alkadienyl) at particular positions (R and R1) of the cyclopentanone structure, allowing the molecule to exhibit both strong aromatic notes and green/lactonic characteristics without requiring complete structural redesign, thus balancing intensity with structural manageability
