Abstract
The synthesis of 5-arylation uracil nucleosides is an imperative challenge. Especially for the method of suzuki reaction using N-unprotected uracil as materials, which holds potential to enhance the yield.
In order to find a more efficient catalyst to increase the yield of aryluracils and aryluridines.
We first constructed the phosphanamine-grafted cellulose (PAGC) from cellulose material. And then prepared the nanocatalyst PAGC/Pd(0) through heating and reducing the mixture of PAGC and Pa(OAc)2.
When using this nanocatalyst to catalyze the Suzuki reaction of 5-iodouracil or 5-iodouridine and aryl heterocyclic boronic acids. The arylation yields have been a significantly improvement.
This means that the resultant nanocatalyst exhibits a remarkable catalytic efficacy for Suzuki arylation of 5-iodouracil and 5-iodouridine.
