  • Method for the organocatalytic activation of carboxylic acids for chemical, reactions using orthosubstituted arylboronic acids
    Patent number: 8822720
    Abstract: The present disclosure describes operationally simple methods for the low temperature, catalytic activation of carboxylic acids for organic reactions, in particular for direct amidation reactions with amines. The methods involve the use of orthosubstituted arylboromc acids of the formula (I), wherein the groups R1 to R5 are as defined herein. In preferred embodiments R1 is halogen. The arylboromc acids catalyze nucleophilic 1,2-addition reactions, conjugate 1,4-addition reactions, and cycloaddition reactions, including Diels-Alder reactions involving ?,?-unsaturated carboxylic acids.
    Type: Grant
    Filed: September 5, 2008
    Date of Patent: September 2, 2014
    Assignee: The Governors of the University of Alberta
    Inventors: Dennis Hall, Olivier Marion, Raed Al-Zoubi
