Divergent synthesis of chiral spiro (isoxazole–isoxazoline) hybrid ligands
摘要:
An efficient synthetic method for chiral (isoxazole-isoxazoline) ligands based on a spiro[4.5]decane framework has been developed. A variety of enantiomerically pure ligands were readily prepared via the Suzuki-Miyaura coupling. The palladium complexes of these ligands have proven to be effective catalysts for the asymmetric Wacker-type cyclization of an alkenyl alcohol. (C) 2008 Elsevier Ltd. All rights reserved.
