N-ethylaminopropanoate (secondary amine) to ethyl 3-F-alkylpropynoate leads in excellent yields to enaminoesters of Z and E configuration respectively. Heterocyclic compounds (pyrrolidone) are obtained from Z enaminoesters in three steps: hydrogenation followed by methylation and cyclisation in alkaline medium.
