Publisher Summary 1, 2, 4-Triazolo [1, 5-a] pyrimidines (TPs) play an important role in
pharmaceutics, agrochemistry, photography, and other fields. They attract attention in …

The present review focuses on the synthesis of two heteroatoms containing sixmembered
heterocyclic compounds, ie, pyrimidine. In this review, a number of pyrimidine derivatives …

This Review describes the existing synthetic approaches for the solid-phase synthesis (SPS)
of differently substituted and fused pyrimidine derivatives. These synthetic strategies are …

Abstract A series of fluorinated 1, 2, 4‐triazolo [1, 5‐a] pyrimidine‐6‐carboxylic acid
derivatives was designed and synthesized as fluoroquinolone analogues. The synthesized …

This paper reviews on application of two Michael reagents-ethyl
ethoxymethylenecyanoacetate (EMCA) and diethyl ethoxymethylenemalonate (DEEM …

The first of the antiinfective agents belonging to the quinolone class was discovered 50
years ago. Since that time many thousands of analogs have been prepared and nearly two …

Abstract Photocatalytic synthesis of 2-amino-4, 6-diarylpyrimidines was carried out by using
nano TiO 2. The method follows a green route by avoiding the use of toxic organic solvents …

Three novel series of 5, 7-diaryl-2-(pyridyl)-1, 2, 4-triazolo [1, 5-a] pyrimidines were prepared
as antibacterial and antifungal agents. The triazolopyrimidines (21-23) am were synthesized …

Syntheses of the target compounds were achieved by reaction of3-amino-5-trifluoromethyl-
1, 2, 4-triazole 1 and diethylethoxymethylenemalonate (DEEM) in glacial acetic acid to …
