are important building blocks for conformationally restrained peptide analogs, was developed. The method relies on a Cu-catalyzed 1,4-addition of Grignardreagents to N-protected 2,3-dehydroproline esters, efficiently prepared in a new one-pot protocol. The 1,4-addition products are obtained with good trans-selectivity (dr 5:1 to 25:1). A nonracemic sample of N-Cbz-3-vinylproline (74% ee) was obtained
