Abstract

Two synthetic sequences towards 'push-pull'-enynes 6 have been investigated starting with ynamines 10 (Schemes 2 and 4). In the successful procedure (scheme 4) Pd(0)-catalyzed coupling of metalated ynamines 11 with 4-bromobutenone or (Z)- and (E)-3-bromoacrylates gives 'push-pull' enynes (E)-6a, (E)-6b, and (Z)-6b (38–63% yields). Crucial spectroscopic data and especially 13C-NMR spectra of 'push-pull' enynes are briefly discussed.
