Studies on the Boulton-Katritzky rearrangement of 3-(2-aminoaryl)-1,2,4- oxadiazoles have led to the identification of additional electronic factors that govern the rearrangement as well as a competitive thermal rearrangement pathway for select substrates
pH Dependent Alternative Ring Closure of Monoacyl 2-Aminobenzamide Oximes. A New 2-Aminobenzimidazole Synthesis

, p. 1652 - 1665 (2007/10/02)
N-Acyl and O-acyl derivatives of 2-aminobenzamide oxime (1) are versatile synthons to prepare different types of heterocycles by intramolecular condensations in which the two nitrogen atoms of the amide oxime moiety, the aromatic amino nitrogen and C-1 of
Ring Transformation of 3-(2-Aminoaryl)-1,2,4-oxadiazoles into 3-Acylaminoindazoles; Extension of the Boulton-Katritzky Scheme

, p. 759 - 766 (2007/10/02)
The ring transformation of 3-(2-aminoethyl)-1,2,4-oxadiazoles (1) into acylaminopyrazolines (2) reported earlier has been extended to 5-substituted 3-(2-aminoaryl)-1,2,4-oxadiazoles (3), (5), (7), and (9).Depending on the reaction conditions and the subst
