Carbohydrate-substituted phosphines are easily obtained in quite good yields by coupling of protected or non-protected D-glucosamine with the corresponding diphenylphosphino acid. These neutral ligands, in association with palladium acetate, are very active catalysts in the Suzuki cross-coupling reaction. The polyhydroxy phosphines are more active than the peracetylated phosphines. The process tolerates electron-rich as well as electron-poor substituents. Excellent turnovers, up to 97 000 are observed. (C) 2003 Elsevier Science B.V. All rights reserved.
