A Cu(I)-catalysed addition and cyclisation sequence has been developed for the synthesis of (E)-alkylidene pyrrolinone derivatives. The reactions incorporate simple α-keto amides and alkynes as substrates, and employ a commercially available Cu(I) catalyst. The process tolerates good variation of both starting materials, and delivers the desired pyrrolinones in good yields, with high levels of stereocontrol
