Enantiomerically pure dihydropyrimidinone 1 reacts with aryl iodides in the presence of catalytic amounts of Pd(OAc)2 and added phosphine to afford dihydropyrimidinone 4, in which a formal conjugate addition of the aryl group to the alpha,beta-unsaturated system has occurred. Application of this methodology to the synthesis of a protected version of the tripeptide portion of the natural product jasplakinolide is presented.
