increased exposure to estrogen has been associated with the risk of breast cancer. substituted benzofuran derivatives with inhibitory effects on estrogen synthesis could be considered as a potential approach to reduce the risk of breast cancer. the study of cytotoxic effects of these compounds has suggested involvement of other mechanisms such as dna damage. in the current study we have investi...
benzofuran as an important heterocyclic compound is extensively found in natural products as well as synthetic materials. since benzofuran drivatives display a diverse array of pharmacological activities, an interest in developing new biologically active agents from benzofuran is still under consideration. this review highlights recent findings on biological activities of benzofuran derivatives...
During a synthesis of coumarins to obtain new candidates for treating Alzheimer's Disease (AD), an unusual rearrangement of a benzopyran group to a benzofuran group occurred, offering a novel synthesis pathway of these benzofuran derivatives. The possible mechanism of the novel rearrangement was also discussed. All of the benzofuran derivatives have weak anti-AChE activities compared with the r...
Abstract Three different reactions were explored leading to the synthesis of various benzofurans. All took place under AcOH catalysis in a one-pot manner. As result, benzoquinone derivatives underwent heteroannulation with either itself or cyclohexanones produce furanylidene-benzofuran benzofuran structures, respectively.
Objective(s): Hybridization of bioactive natural and synthetic compounds is one of the most promising novel approaches for the design of hit and lead compounds with new molecular structures. In this investigation, a series of novel hybrid structures bearing quinazolinone, benzofuran and imidazolium moieties were designed and synthesized. Materials and Methods:Novel hybrid compounds were prepare...
The addition of an allenyl indium intermediate to chiral N-tert-butanesulfinyl imines 7 proceeds with high levels of diastereocontrol. The resulting homopropargylic amine derivatives 10 were transformed into 2-(2-aminoalkyl)benzofuran and indole derivatives 13 and 19, after Sonogashira coupling with o-iodophenol or o-iodoaniline, followed by formation of the heteroaromatic ring through an intra...
