Publisher Summary This chapter provides information on five membered ring systems with more than one N atom. Applications of imidazole- and 1,2,3-benzotriazole-containing reagents to a wide array of synthetic operations remained a constant theme. The chapter discusses the following: (1) pyrazoles and ring-fused derivatives; (2) imidazoles and ring-fused derivatives; (3) 1,2,3-triazoles and ring-fused derivatives; (4) 1,2,4-triazoles and ring-fused derivatives; and (5) tetrazoles and ring-fused derivatives. The synthesis of the pyrazole core structure has been approached from many angles. The classical method involves the reaction of 1,3-difunctional species with hydrazine derivatives. β-Chlorovinylaldehydes were converted to pyrazolo[3,4- b ]quinolines and pyrazolo[3,4- c ]pyrazoles, respectively. 1,2-Diamines have been useful precursors for the syntheses of benzimidazoles. Treatment of o -phenylenediamines with hexachloroacetone under sonication provided substituted bisbenzimidazoles in good yields. Polymer-supported benzotriazoles were employed as catalysts in the synthesis of tetrahydroquinolines by condensation of aldehydes with aromatic amines and as synthetic auxiliaries and traceless linkers for the combinatorial synthesis of unsymmetrical ureas.
