The synthesis of 2 via our microwave method proved to be practical, and we therefore sought to explore the reaction scope further. To date, the synthesis of uracil derivatives using this type of cyclocondensation reaction has not been reported. Herein, we report the scope of the microwave cyclocondensation to prepare uracil derivatives using bis(pentafluorophenyl)imidodicarbonate. ... The results from Table 1 show that bis( ...
