Abstract

C5-Aryl/heteroaryl uracil-based compounds have attracted continuous interest because of their wide biological potential. In this review, we outline the primary synthetic methods used to prepare designated uracils, various combinations of which have been used to synthesize target compounds with potential biological activities. The significance of each approach and its limitations are also summarized.
