An efficient method allows a stereospecific synthesis of trans-substituted cyclopentene derivatives via the ring-opening rearrangement of readily available MCP alkenyl derivatives good yields. This transformation might proceed through a fast concerted pericyclic process rather than a simple radical pathway or an ionic pathway.
