PdII/PdIV Catalytic Enantioselective Synthesis of Bicyclo[3.1.0]hexanes via Oxidative Cyclization of Enynes

The first asymmetric PdII/PdIV catalysis has been achieved by employing the combination of a hypervalent iodine reagent and a chiral ligand, SPRIX. Enantioselective cyclization of enyne derivatives catalyzed by the Pd−i-Pr-SPRIX complex furnished lactones bearing a bicyclo[3.1.0]hexane skeleton with...

description The first asymmetric PdII/PdIV catalysis has been achieved by employing the combination of a hypervalent iodine reagent and a chiral ligand, SPRIX. Enantioselective cyclization of enyne derivatives catalyzed by the Pd−i-Pr-SPRIX complex furnished lactones bearing a bicyclo[3.1.0]hexane skeleton with up to 95% ee.
