STEREO CONTROLLED SYNTHESIS OF (E,Z)-DIENALS VIA TANDEM RH(I) CATALYZED PROPARGYL CLAISEN REARRANGEMENT
20170129865 · 2017-05-11 ·

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.
