Abstract
Abstract Alkyl, allyl, and propargyl β-iodopropionates undergo a cyclopropanation by the reaction with zinc-copper couple and TBDMSCl in THF to give 1-alkoxy-, 1-allyloxy-, and 1-propargyloxy-1- tert -butyldimethylsiloxycyclopropanes in moderate or good yields. β-Iodo-α-methylpropionates 2 and 6 provide trans - 5 and trans - 8 selectively, while β-iodobutyrates 3 and 7 furnish cis - 5 and cis - 8 selectively.
