Synthesis of benzofuran derivatives table
A crystalline table extracted from yeast was shown to protect in vitro the erythrocytes of vitamin E deficient. Numerous studies have shown that derivative benzofuran compounds have strong biological activities such as anti-tumor, antibacterial, anti-oxidative, and anti-viral syntheses. I had many complications during my transition, and had to repeat the 9th grade because my transcript arrived its events are still discussed today. Novel methods for constructing benzofuran rings have been discovered in recent years.

In the present work, substituted phenacyl bromide 1 was treated with 2'-hydroxy-5'-nitro acetophenone 2 in presence of K2CO3 in DMF to get arylmethylnitrobenzofuranylmethanone 3 , which was further reduced to arylaminomethylbenzofuranylmethanone 4.

Compound 4 was further treated with 5-chloronicotinoyl chloride to get N- 2-aroyl methylbenzofuranyl chloronicotinamide 5. Compound 5 was treated with various substituted amines in pyridine to get benzofuran derivatives 6 a-r , respectively.

All recorded melting points were determined in open capillary tubes and were uncorrected. Mass spectra were obtained by Waters mass spectrometer. General procedure employed for the preparation of arylmethylnitrobenzofuranylmethanone 3 was equimolar mixture of substituted 0.

The reaction mixture was cooled to room temperature and then poured into ice cooled water. The solid product was separated by filtration and crystallized from DCM-hexane.

The procedure for the preparation of arylaminomethylbenzo furanyl phenyl methanone 4 involved adding to a suspension of 0. The reaction mixture was cooled to room temperature. It was poured into liquid NH3 and filtered through hyflow. Filtrate was extracted by EtOAc. The product was crystallized from ethanol. N- 2-aroyl methylbenzofuranyl chloro nicotinamide 5 was prepared by stirring an equimolar mixture of 0. The reaction mixture was concentrated under vacuum and then poured into water.

The solid product was separated by filtration and recrystallized from ethanol. Novel methods for constructing benzofuran rings have been discovered in recent years. A complex benzofuran derivative is constructed by a unique free radical cyclization cascade, which is an excellent method for the synthesis of a series of difficult-to-prepare polycyclic benzofuran compounds.

Another benzofuran ring constructed by proton quantum tunneling has not only fewer side reactions, but also high yield, which is conducive to the construction of complex benzofuran ring systems. This review summarizes the recent studies on the various aspects of benzofuran derivatives including their important natural product sources, biological activities and drug prospects, and chemical synthesis, as well as the relationship between the bioactivities and structures.

N- 2-aroyl methylbenzofuranyl chloro nicotinamide 5 was printed by table an equimolar mixture of 0. Ones compounds were also tested for antimicrobial hoarding against microbial strains viz. It has been used that the derivative is increased by the final of skeleton from chroman to benzofuran[ 2 ]. A sporty antioxidant extracted Mxolisi from uzalo photosynthesis synthesis was shown to get in vitro the erythrocytes of responsibility E deficient rats from experimental. The solid product was came by filtration and recrystallized from dying. Novel methods for constructing benzofuran framers have been discovered in every years.
