A new type of chiral sulfoxide-phosphine ligands have been developed by a rational combination of two privileged scaffolds for Pd-catalyzed asymmetric allylicalkylation reactions. Under optimized conditions, generally high yields (up to 97%) and excellent enantioselectivities (up to >99% ee) were obtained.
synthesized in very good enantio- (up to 97% ee) and diastereoselectivities (dr up to 7.6:1) with contiguous quaternary and tertiary stereogenic centers by employing tartrate derived bi(oxazoline) in Pd-catalyzed allylation of 3-OBoc-oxindole. Synthetic utility of 3-allyl-3-hydroxyoxindole was demonstrated by synthesizing a highly substituted spiro(oxindole-3,2′-tetrahydrofuran) derivative in good yield and
