Abstract:
Thiazolopyrimidnes are considered one of the most interesting classes in heterocyclic chemistry due to their pharmaceutical importance. Herein, we report the synthesis of some new heterocyclic compounds containing thiazolopyrimidine starting from compound (1) which was previously prepared in literature. The starting compound was allowed to react with different alkylating agents such as chloroacetone, chloroacetyl chloride, and phenacyl bromide to afford derivatives (2-4). Compound (5), benzylidene derivative, was obtained by the reaction of compound (2) with benzaldehyde while amino-dicarbonit

Thiazolopyrimidine 2 was obtained from the reaction of dihydropyrimidinone with chloroacetic acid and benzaldehyde. Thiazolopyrimidine 2 containing an α,β-unsaturated ketonic function [-CH=CH-CO-] has been used as a component of Michael addition with an equimolar amount of dinucleophiles to give a series of novel tetracyclic pyrimidine derivatives. Treatment of thiazolopyrimidine 2 with uracil, aminotriazole, cyanoacetic acid hydrazide, o-phenylenediamine or diaminopyridine afforded the corresponding pyridopyrimidine, triazolopyrimidine, pyrazolone, benzodiazepine and triazepine derivative, re

Abstract:
Thiazolopyrimidine is a nitrogen and sulphur containing heterocyclic aromatic molecule. The bicyclic compound is made by fusing two aromatic rings, thiazole and pyrimidine and replacing one carbon atom with nitrogen and sulphur. The current present work covers a wide range of methods for synthesizing thiazolopyrimidine and its derivatives using a variety of catalysts, solvent medium and microwave irradiation with a goal of achieving a high yield and rapid separation of the product. This article describes the evolution of thiazolopyrimidine as antimicrobial, antiviral, anti-Parkinson, anticance

Abstract:
This study investigated the interaction between selected 4- oxothiazolidine-2-ylidene thioamides 2a-c and iodine in acetone. The interaction followed two main reaction pathways: (1) iodine-mediated cyclization resulting in the formation of thiazolopyrimidine 7, and (2) electrophilic iodine attack on the thioamide sulfur atom, producing a complex mixture of iodine adducts. Due to the equilibrium of Z/E isomerization being strongly shifted to the Z-isomer in polar solvents, only the thioamide (E)-2b successfully formed thiazolopyrimidine 7. The other two derivatives, (Z)-2a and (Z)-2c, followed

Background:The present research describes a mild and efficient method for the synthesis of 3,4-dihydropyrimidine-2(1H)-thiones and thiazolopyrimidine via multi-component reactions using FeCo2O4 nanoparticles. It was found that FeCo2O4 nanoparticles act as a powerful and effective catalyst. The prepared catalyst was characterized by the various spectroscopic techniques.Objective:The three-component reaction of thiourea, aromatic aldehydes and ethyl acetoacetate was catalyzed by FeCo2O4 nanoparticles.
