Sequential hydrozirconation/cyclization of dienes, a new route toward trans 2-substituted vinylcyclopentanes

Clergue, Sebastien,Vasse, Jean-Luc

supporting information, p. 1506 - 1509 (2014/04/03)

The diastereoselective synthesis of trans-2-substituted vinylcyclopentanes is described. The method is based on the intramolecular coupling of 7-methoxy-1,5-dienes involving a sequential activation of the C=C double bonds via hydrozirconation and TMSOTf-promoted allylation.
