Enantiomericallypure 2-iodocyclopropylboronic esters 6 and 8 have been synthesized from the readily available allylic alcohol 2via an oxidation-radical decarboxylation sequence. These unique buildingblocks have been demonstrated to be versatile intermediates for a consecutive Suzuki-coupling with aryl-, heteroaryl-, alkenyl-, and cyclopropylboron derivatives (1 example each).
