2-substituted benzoxazole preparation method of compound
-
Paragraph 0048, (2016/10/20)
The invention relates to a preparing method of 2-substituted benzoxazole compounds. The compounds are obtained by reaction of products obtained by reaction of acyl chloride and o-nitrophenol or derivatives thereof under catalyzing of reducing agent ammonium formate, a solvent and palladium-containing agents. According to the method, the reaction condition is mild, environment is protected, raw materials are rich and easy to obtain, operation is easy, yield is high, and various kinds of performance are optimized.

A new procedure for regioselective functionalization of sensitive alkyl aryl ethers has been proposed as an alternative to picrate and sulphonamide derivatives.The procedure is based upon their reaction with cerium(IV) ammonium nitrate (CAN) and gives good yields of nitro substituted ethers, affording one pot synthesis of hitherto unknown 1-isopropoxy-4-nitronaphthalene, 1-butoxy-4-nitronaphthalene, 2-isopropoxy-6-nitronaphthalene and 2-butoxy-6-nitronaphthalene.A plausible mechanism has been suggested.

, p. 899 - 900 (2007/10/02)
A mild but efficient method for the drivatization of esters has been developed by their reaction with cerium(IV)ammonium nitrate in acetic acid medium.The method provides a facile synthesis of 2-nitro-, 5-nitro-1-napthyl acetates, 4-nitro-1-naphthylbenzoa

Reaction of cerium(IV) ammonium nitrate with some naphthyl ethers has been studied as a substitute to traditionally used hydrolytic cleavage method for their identification.One-pot, one-step synthesis of 2,2'-dinitro-1,1'-diethoxy-4,4'-bisnaphthalene; 2,2'-diethoxy-8-nitro-4,4'-bisnaphthalene; 1,8-dinitro-2-methoxynaphthalene; 2-methoxy-8-nitronaphthalene; 1-methoxy-4-nitronaphthalene; 1-ethoxy-4-nitronaphthalene; 4-nitro-1-naphthylbenzoate; 2-methoxy-6-nitronaphthalene; 1-nitro-2-naphthylbenzoate are described.
