Abstract

Direct microwave-assisted iodination of several pyrimidinones and pyrimidine nucleosides with N-iodosuccinimide to give the corresponding 5-iodo derivatives is described. Application of this reaction to polymer-bound pyrimidinones was also investigated.

The same results can be obtained using a domestic oven (LG Electronics, model: MS-192A) with a maximum emitted power of 800 watts. The temperature of the reaction mixture at the end of microwave irradiation was found to be 70-100 °C.
