Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method to synthesize an (E,Z)-dienal compound having structure (V), the method comprising: contacting a compound having structure (IV) with a catalyst comprising Rh(I) to thereby prepare the compound having structure (V); wherein the compounds having structures (IV) and (V) have the following structures: wherein R 1 is selected from the gr…
