3,3-diethyl-2-oxa-spiro[4.5]dec-7-ene Compounds for Complex Fragrance Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fragrance industry lacks new chemical entities that can create unique and complex odor profiles, particularly fruity, green, and woody notes, to enhance or modify perfumes, colognes, and personal care products effectively.
Innovation Solution
The development of novel 3,3-diethyl-2-oxa-spiro[4.5]dec-7-ene compounds, which can be used in olfactory acceptable amounts to improve, enhance, or modify fragrance formulations, providing a complex and desirable scent through their fruity, green, and woody notes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new chemical entities are developed to create unique odor profiles, then fragrance complexity and desirability are improved, but research and development time and cost increase
Solution Approach 1:
The patent applies parameter changes by systematically varying the R1 substituent groups on the core 3,3-diethyl-2-oxa-spiro[4.5]dec-7-ene structure. By changing the chemical parameters (different alkyl, aryl, heteroaryl groups at positions 2, 4, 6, 8), the invention generates multiple compounds with distinct odor profiles (fruity, green, woody notes) from a single core structure, thus improving fragrance complexity through controlled parameter variation.
2Adaptability or versatility
If new chemical entities are developed to create unique odor profiles, then fragrance complexity and desirability are improved, but manufacturing and synthesis complexity increase
Solution Approach 1:
The patent employs universality by designing a core 3,3-diethyl-2-oxa-spiro[4.5]dec-7-ene structure that serves as a multi-functional platform. This single core structure can generate multiple fragrance compounds with different odor characteristics by simply changing the R1 substituent, thereby reducing synthesis complexity compared to developing entirely new molecular frameworks for each fragrance note.
Solution Approach 2:
The invention uses parameter changes to systematically modify the R1 groups (methyl, ethyl, propyl, butyl, phenyl, naphthyl, etc. at various positions) while maintaining the core spiro structure. This approach allows for controlled variation of fragrance properties through substituent changes rather than complete structural redesign, balancing fragrance complexity with manageable synthesis complexity.
