Cyclohexenyl Methanol Esters for Multi-Faceted Odor Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fragrance industry lacks fragrance compounds with improved organoleptic properties, and there is a need for new chemical structures that can enhance or modify the odor characteristics of existing fragrance compositions.
Innovation Solution
The development of fragrance compounds, such as cyclohex-3-en-1-ylmethyl 2-hydroxypropanoate, cyclohex-3-en-1-ylmethyl 3-oxobutanoate, and their stereoisomers, which can be used alone or incorporated into fragrance compositions to provide multi-faceted odors and enhance the odor properties of consumer products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If new fragrance compounds are developed to improve organoleptic properties, then odor characteristics are enhanced, but research and development time and resources increase
Solution Approach 1:
The patent applies parameter changes by systematically varying the R group in Formula I (different hydroxy-containing groups such as CH(OH)CH3, CH2(CO)CH3, and CH2OH) to create multiple fragrance compounds with improved organoleptic properties. This approach allows for efficient exploration of chemical space and identification of optimal fragrance molecules without extensive de novo synthesis.
2Adaptability or versatility
If new chemical structures are created to provide unique odor characteristics, then fragrance versatility is improved, but synthesis complexity increases
Solution Approach 1:
The patent employs segmentation by dividing the fragrance compound into distinct functional segments: the cyclohex-3-en-1-ylmethyl core structure and the variable R group containing hydroxy functionality. This modular approach allows independent optimization of each segment and simplifies synthesis by enabling separate preparation and subsequent coupling of fragments.
Solution Approach 2:
The patent creates composite fragrance molecules by combining the cyclohex-3-en-1-ylmethyl scaffold with various hydroxy-containing groups (R = CH(OH)CH3, CH2(CO)CH3, or CH2OH). This composite structure integrates different functional properties within a single molecule, achieving versatile odor characteristics while maintaining reasonable synthesis complexity.
