3-Phenylbenzo[c]isoxazoles were synthesized by non-catalytic thermolysis of 2-azidobenzophenones in dry xylene with quantitative yields. The trace content of water in solvents reduces the yields of the reaction products. 2-Azidobenzoic acid esters are sta
Catalyst-free cyclization of anthranils and cyclic amines: One-step synthesis of rutaecarpine

An efficient synthesis of a variety of quinazolinone derivatives via a direct cyclization reaction between commercially available anthranils and cyclic amines is described. The developed transformation proceeds with the merits of high step- and atom-efficiency, a broad substrate scope, and good to excellent yields, without additional catalysts, and offers a practical way for the preparation of rutaecarpine and its derivatives with structural diversity.
Nucleophilic substitution of hydrogen in activated nitroarenes by phenylacetonitrile carbanion
Orlov,Sokovikov,Kotov,Starikov
, p. 1735 - 1738 (2007/10/03)
General relations holding in nucleophilic substitution of hydrogen in para-substituted nitroarenes by phenylacetonitrile carbanion were analyzed in terms of the Klopman reactivity indices. Requirements to the substrate structure were determined, which restrict the scope of application of this method to synthesis of 2,1-benzisoxazole derivatives.
