    MICROWAVE-ASSISTED SOLVENT-FREE ARYLATION OF AMINO ACIDS WITH HALOGENOBENZENES
    (journals.chemsociety.org.ng, 2018-06-21) Sowole, M.A.; Adebisi, A.B.; Olasupo, I.A.; Izunobi, J.U.; Familoni, O.B.
    The solventless microwave-assisted arylation and heteroarylation of different aliphatic and cyclic amino acids 2a–e were carried out on activated, substituted o-nitrohalogenobenzenes 1a–h and 2-chloro-3-nitropyridine 1i, in the presence of potassium carbonate and potassium fluoride for 0.5 h at 70 W, to give substituted N-(o-nitrophenyl)amino-2-carboxylic acid 3–16 and N-(m-nitropyridyl)amino-2-carboxylic acid 17–18 adducts in yields ranging from 5–98% .
