Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a cost-effective method to prepare major and minor cannabinoids while minimizing the presence of THC.
Innovation Solution
A process involving the contact of a compound of Formula I, or its salt, with a terpene-based electrophile under specific conditions to produce cannabinoids, utilizing resorcinol carboxylic acids as blocking or protecting groups to reduce byproducts and include preferred terpenes like olivetolic acid for efficient synthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods are used to prepare cannabinoids, then production cost and yield are affected, but the presence of THC increases and manufacturing precision deteriorates
Solution Approach 1:
The patent extracts and removes the harmful element (THC) from the cannabinoid production process by using resorcinol carboxylic acids as blocking groups that specifically prevent THC formation while allowing desired cannabinoid synthesis to proceed
Solution Approach 2:
The patent changes the chemical parameters of the synthesis process by introducing resorcinol carboxylic acids with specific R1 substituents (C1-C10 alkyl, C2-C10 alkenyl, or C2-C10 alkynyl groups) to control reaction outcomes and achieve precise THC content control
2Manufacturing precision
If resorcinol carboxylic acids are used as blocking groups, then byproduct reduction and manufacturing precision improve, but process complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-attaching resorcinol carboxylic acids to the cannabinoid precursor molecules before the main synthesis reaction, creating blocking groups that prevent unwanted reactions and reduce byproducts in advance
Solution Approach 2:
The resorcinol carboxylic acids serve as intermediary blocking groups that mediate between the desired synthesis pathway and unwanted side reactions, selectively preventing THC formation while allowing target cannabinoid production
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for the efficient production of cannabinoids with minimal THC content, offering advantages in yield, processing, and purification, enabling the production of both acidic and neutral cannabinoids with high purity.
Implementation Method 1
contacting a compound of Formula I with a terpene-based electrophile under conditions suitable to provide a cannabinoid. Without being bound by theory, the carboxyl group of the resorcinol carboxylic acid of formula 1, acts as a blocking or protecting group for an electrophilically active position of the compound
