Abstract
New phosphino-ferrocene carboxylic acids with only planar chirality (Sp)-3 and (Sp)-4 have been synthesized conveniently from (S,Sp)-5 and (S,Sp)-7. T hey were used as ligands in palladium-catalyzed allylic alkylation of cyclo alkenyl acetates. With ligand (Sp)-4, high yield and good ee were given for reactions of a series of cycloalkenyl acetates and nucleophiles. (C) 2001 Elsevier Science B.V. All rights reserved.
