An iron-catalyzed sustainable, economically affordable, and eco-friendly synthetic protocol for the construction of various trisubstituted pyrimidines is described. A wide range of trisubstituted pyrimidines were prepared using a well-defined, easy to prepare, bench-stable, and phosphine-free iron catalyst featuring a redox-noninnocent tridentate arylazo pincer under comparatively mild aerobic conditions via dehydrogenative functionalization of alcohols with alkynes and amidines.

A convenient metal-free synthesis of unsymmetrical 2-aminopyrimidines from imidazolate enaminones has been developed. In this procedure, various structural 2-aminopyrimidines, as well as 4,5-dihydroisoxazol-5-ols and pyrazoles were synthesized in moderate to excellent yields. A plausible mechanism was also proposed for the cascade reaction. This method represents an effective strategy towards the synthesis of unsymmetrical 2-aminopyrimidines.

Photocatalytic synthesis of 2-amino-4,6-diarylpyrimidines was carried out by using nano TiO2. The method follows a green route by avoiding the use of toxic organic solvents and tedious experimental conditions. Compared with conventional methods the present strategy offers excellent yield under UV irradiation for a period of 20 min in ethanolic medium. Only a small quantity of nanocatalyst (1 mol%) is sufficient to achieve the completion of the reaction. The nanocatalyst can be reused up to four reaction cycles without much loss in the activity.
