| Abstract/Summary |
The effect of six different P,N-ferrocenyl ligands having both central and planar chirality on the stereoselectivity of Pd(0)-catalyzed allylation of methyl or (1R,2S,5R)-(-)-menthyl (diphenylmethylene) glycinate was studied. Just moderate yields of the allylation products were isolated. The highest stereoselectivity was achieved with the ligand (R,pS)-BPPFA, namely 25.5 % ee at allylation of methyl glycinate. It was proved that in allylation of (1R,2S,5R)-(-)-menthyl (diphenylmethylene) glycinate the ester chiral auxiliary has a dominant effect.
