Enantiomerically Pure Cyclopropane Building Blocks: Synthesis and Transformations of 2‐Iodocyclopropylboronic Esters

Abstract

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