摘要

Coupling of protected or non-protected d-glucosamine with o-or p-(diphenylphosphino) benzoic acid generates carbohydrate-substituted phosphines in quite good yields. The catalytic performance of these new neutral ligands is demonstrated in the Suzuki cross- coupling reaction. The polyhydroxy phosphines are more active than the peracetylated phosphines, and the process tolerates electron-rich as well as electron-poor substituents. ...
