The Heck reaction of alkenes bearing in δ position an enolate of β-diester, βketo ester or β-sulfonyl ester leads to cyclopentanes issued from the intramolecular displacement of the carbone sp3-palladium bond by this enolate. This cyclisation is not observed when the enolate is in β or ε position or in the case of a δ-ethylenic amine and βelimination products are only obtained.
