Summary: | 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. Excellent turnovers are observed, and the catalyst can be recycled.
Glucosamine-based phosphines efficiently catalyzed the Suzuki reaction in water, the recycling of the catalyst being possible. |
