Stereospecific synthesis of (Z) or (E)-3-methylalk-2-enoic acids

Abarbri,Parrain,Duchene

, p. 2469 - 2472 (1995)

The palladium catalysed coupling of organozinc or organotin reagents with 3-iodobut-2(or 3)-enoic acid is stereoselective and affords Z (or E)-3-methylalk-2-enoic acids. The method was applied to the synthesis of the E and Z stereoisomers of ocimenones and pseudo-tagetones.
