Preparation and Cyclopropanation of 2- and 3-Iodoalk-2-en-1-ols: Synthesis of Functionalized, Stereodefined Iodocyclopropanes
31 December 2000 (online)
The iodoalkenes 10-15 and 29-32 were prepared by use of a variety of synthetic methods. Cyclopropanations of these substances with the reagent derived from chloroiodomethane (ClCH2I) and diethylzinc (Et2Zn) were investigated. In the absence of ”interfering” functional groups, these reactions are clean and produce the corresponding, functionalized iodocyclopropanes in good to excellent yields.
