A number of thiazolopyrimidines (II-VII) were prepared through interaction of 6-methyl-4(4?-chlorophenyl)-2-thioxo-1,2,3,4-tetrahydropyrimidine-5- carboxylic acid ethyl ester (Ia) with many reagents. The antifungal activity of all prepared compounds have been determined using Dithane M-45 as a standard fungicide. Some compounds showed a high fungicidal activity equivalent to that of the standard towards Aspergillus niger and Aspergillus ochraceus. Also some biologically active compounds were subjected to gamma irradiation and the structures are stable.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2213-63-0 is helpful to your research. Electric Literature of 2213-63-0

A significant number of important acyl-transfer reactions, such as direct acylation, ortho acylation, heteroatom acylation, and a diversity of cyclization reactions using the title compound as a key starting material, have been described in recent years. Just like a sleeping beauty, alpha-oxocarboxylic acids were awakened from a 17-year sleep to become important reagents in classical and new acylation reactions. The greener characteristic of the coproduct formed in reactions using alpha-keto acid (only CO2), together with its versatility as a building block in catalytic organic synthesis, accredit it as a candidate to green acylating agent, an alternative to acyl chloride, and other acyl-transfer reagents. This review presents the impressive breakthroughs achieved mainly in the past decade in the development of new catalytic reactions for the formation of C-C, C-N, and C-S bonds using alpha-keto acids.
