β¦ Synopsis
cis 2-Iodomethyl-3-hydroxytetrahydrofurans have been obtained in high yields and in high selectivities by treatment of 4-penten-1.3-diols with iodine (ether-H20, NaHC03). Recently many methodologies have been developed for the stereocontrolled preparation of substituted tetrahydrofurans. 1 Here we describe the very efficient and stereoselective synthesis of cis 2-iodomethyl-3-hydroxytetrahydrofurans
