The synthesis of enantiomerically pure cyclopropyl boronic esters 12a-d and 13a-d has been achieved. The high-yielding process involves the condensation of readily available alkenyl boronic acids la-d with (2R,3R)-1,4-dimethoxy-(1R,2S)-4c+d and (lS,2S)-4a+bl(lS,2R)-4c+d, respectively, 1,1,4,4-tetrap
Diastereoselective Synthesis of Cyclopropyl Boronic Esters. -A simple and efficient protocol for the conversion of 1-alkynes to 2-alkylcyclopropanols is described. Thus, 1-alkyne-derived alkynyl boronic esters (I) are converted to chiral tartrates (IV) and then subjected to cyclopropanation providi
