EnglishStereoisomerically pure (Z)- and (E)-alkyl 2-bromo-3-(hetero)arylpropenoates, (Z)- and (E)-2, have been efficiently and selectively prepared by Pd(0)-mediated cross-coupling reaction between (hetero)arylzinc halides, 5, and easily available (Z)- and (E)-alkyl 2,3-dibromopropenoates, (Z)- and (E)-4, respectively. Compounds (Z)- and (E)-2 serve as useful precursors to stereoisomerically pure trisubstituted (E)- and (Z)-alpha,beta-unsaturated esters, respectively.
