Synthesis and anticancer activity of novel quinazolinone-based rhodanines
BACKGROUND Rhodanines and quinazolinones have been reported to possess various pharmacological activities. RESULTS A novel series of twenty quinazolinone-based rhodanines were synthesized via Knoevenagel condensation between 4-[3-(substitutedphenyl)-3,4-dihydro-4-oxoquinazolin-2-yl)methoxy]substituted-benzaldehydes and rhodanine. Elemental and spectral analysis were used to confirm structures...
متن کاملA Rapid Combinatorial Library Synthesis of Benzazolo[2,1-b]quinazolinones and Triazolo[2,1-b]quinazolinones
Benzazolo [2,1-b]quinazolinones and triazolo[2,1-b]quinazolinones were synthesized in high yields by the condensation reaction of an aldehyde and a cyclic β-diketone with 2 - aminobenzimidazole, 2 - aminobenzothiazole or 1, 2, 4 - triazole derivatives in 1 - butyl - 3 -methylimidazolium bromide as an ionic liquid under classic heating conditions within 5-60 minutes.
متن کاملRecent developments in the chemistry of quinazolinone alkaloids.
Quinazolinones, an important class of fused heterocyclic alkaloids has attracted high attention in organic and medicinal chemistry due to their significant and wide range of biological activities. There are approximately 150 naturally occurring quinazolinone alkaloids known till 2005. Several new quinazolinone alkaloids (∼55) have been isolated in the last decade. Natural quinazolinones with ex...

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولPalladium-catalyzed dicarbonylative synthesis of tetracycle quinazolinones.
An interesting procedure for the synthesis of isoindolo[1,2-b]quinazolin-10(12H)-ones has been developed. Starting from commercially available 2-bromoanilines and 2-bromobenzyl amines, with the assistance of a palladium catalyst, the desired products were isolated in good yields. Notably, this procedure proceeded in a highly selective manner; two molecules of CO were incorporated into the subst...
