benzofuran การใช้

• The benzofuran ring and the benoxazole ring are indicated in red.
• For instance, photochemical rearrangement of its mono-epoxide forms benzofuran.
• The asymmetric hydrogenation of furans and benzofurans has so far proven challenging.
• It is banned by a blanket law on benzofurans and related compounds.
• For example, psoralen is a benzofuran derivative that occurs in several plants.
• Benzofuran is the " parent " of many related compounds with more complex structures.
• The molecule contains a benzofuran element associated with a benzylidene linked in position 2.
• This also includes napthalenes, benzofurans and indoles.
• It acts as an agonist for the nitrogen replaced by oxygen, making dimemebfe a benzofuran derivative.
• It is also known as isocoumaran, or 1, 3-dihydro-2-benzofuran.
• "' Benzofuran "'is the heterocyclic compound consisting of fused benzene and furan rings.
• Some Ru-NHC complex catalyze asymmetric hydrogenations of benzofurans and furans . with high levels of enantioinduction.
• A variety of substituted aromatic rings can be prepared using this method including : phenols, naphthalenes, benzofurans, benzothiophenes, indoles, and carbazoles.
• Budiodarone only differs in structure from amiodarone through the presence of a " sec "-butyl acetate side chain at position 2 of the benzofuran moiety.
• On 10 June 2013, a total of 10 benzofuran and indole analogues and four NBOMe hallucinogens were classified as Temporary Class Drugs in the UK following an ACMD recommendation.
• Intramolecular cyclization of ortho-alkynylphenyl ethers leads in the presence of P 4-" t "-Bu under mild conditions without metal catalysts to substituted benzofurans.
• Another large class of heterocycles are fused to benzene rings, which for pyridine, thiophene, pyrrole, and furan are quinoline, benzothiophene, indole, and benzofuran, respectively.
• On March 5, 2014 the UK Home Office announced that 5-MAPB would be made a class B drug on 10 June 2014 alongside every other benzofuran entactogen and many structurally related drugs.

• It falls under the category of research chemicals, sometimes called " legal highs . " Because 6-APB and other substituted benzofurans have not been explicitly outlawed in some countries, they are often technically legal, contributing to their popularity.
