  • Stereo controlled synthesis of (E,Z)-dienals via tandem Rh(I) catalyzed propargyl claisen rearrangement
    Patent number: 9758499
    Abstract: A novel Rh(I)-catalyzed approach to synthesizing functionalized (E,Z) dienal compounds has been developed via tandem transformation where a stereoselective hydrogen transfer follows a propargyl Claisen rearrangement. Z-Stereochemistry of the first double bond suggests the involvement of a six-membered cyclic intermediate whereas the E-stereochemistry of the second double bond stems from the subsequent protodemetallation step giving an (E,Z)-dienal. The reaction may be represented by the following sequence.
    Type: Grant
    Filed: January 4, 2017
    Date of Patent: September 12, 2017
    Assignee: The Florida State University Research Foundation, Inc.
