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.

Diels-Alder reactions of Ethyl F-alkyl propynoates with different substituted furans and pyrroles were realised.Different products were obtained according to the substituents of the heterocyclic dienes and more surprisingly with the length of the F-alkyl chain.

The Diels-Alder reactions of ethyl 3-F-alkylpropynoates with cyclopentadiene, tetracyclone (tetraphenylcyclopentadienone) and anthracene have been achieved.The corresponding addition products were obtained with cyclopentadiene and anthracene. With tetracyclone, ethyl 2-F-alkyl-3,4,5,6-tetraphenylbenzoate was obtained.
