Diastereo-Differentiation during 2,4-Pentanediol Tethered Simons-Smith Type Cyclopropanation: Reaction Species of Hydroxyl Group Directed Zinc Carbenoid Addition

The predominant formation methods for the diastereodifferentiating species of zinc carbenoid addition to the 1cyclohexenyl ether carrying the 2,4-pentanediol moiety were established. The species were found to include two zinc atoms and one carbenoid carbon at the hydroxyl group.
