benzofuran moiety were prepared from the reaction of 2‐(2‐phenylhydrazono)‐1‐(5‐bromobenzofuran‐2‐yl)‐2‐chloroethanone with each of potassium thiocyanate, potassium selenocyanate, alkyl carbodithioate, and pyrmidine‐2‐thione derivatives. All the newly synthesized compounds were confirmed by elemental analysis, spectral data, and alternative route synthesis whenever possible.

increase in the incidence and mortality of colorectal cancer, it is necessary to develop new strategies in the search for new alternatives against this disease. Hence, we designed and synthesized a new series of monastrol/melatonin hybrids and evaluated them in vitro and in silico to determine the potential of these new chemical entities on this type of cancer. To achieve this goal, the different compounds

An efficient one-pot method to synthesize thiazolo[3,2-a]pyrimidine derivatives has been developed. The method involves the temperature controlled functionalization-annulation of 5-ethoxycarbonyl-6-methyl-4-aryl-3,4-dihydro-2(1H)-pyrimidin-2-thione (DHPM) derivatives with in-situ generated bromo-ketones received by reaction of different α-H carbonyl compounds with bromine.
已经开发了一种有效的一锅法合成噻唑并[3,2- a ]嘧啶衍生物。该方法涉及温度控制的5-乙氧基羰基-6-甲基-4-芳基-3,4-二氢-2(1 H)-嘧啶-2-硫酮(DHPM)衍生物的官能化-环化反应。不同的α-H羰基化合物与溴反应得到的酮。
Synthesis and in vitro antimicrobial studies of thiodihydropyrimidine derivatives
In the present study, a series of thiodihydropyrimidine derivatives were synthesized from different substituted aromatic aldehydes, ethyl acetoacetate, and urea/thiourea using a bimetallic TUD‐1 catalyst. The structures of all the synthesized compounds were characterized by melting point determination, thin layer chromatography (TLC), infrared (IR), 1HNMR, and 13C‐NMR values. All the synthesized compounds
