Efficient Synthesis of Conjugated (2E)- or (2Z)-En-4-ynoic Acids and (2E,4E)- or (2Z,4E)-Dienoic Acids via Palladium-Catalysed Cross Coupling

All articles of this category ( E )- or ( Z )-Enynoic acids and (2 E ,4 E )- or (2 Z ,4 E )-dienoic acids can be obtained in good yields under mild conditions through palladium-catalysed cross coupling of ( E )- or ( Z )-3-iodoprop-2-enoic acid with alkynylzinc or vinyltin reagents. iodopropenyl acid - conjugated enynoic acids - conjugated dienoic acids - organozinc reagents - vinyltins - palladium-catalysed cross-coupling reactions
