Hydrazinobenzoic acid

The polymer-assisted solution-phase (PASP) synthesis of a 192-member group of 1,5-biaryl pyrazoles from 1,3-diketones and 4-hydrazinobenzoic acid as precursors has been reported <2004JC0332>. Condensation of aromatic or aliphatic esters with resin-supported sulfonamides 527, followed by cyclization with hydrazines, activation with trimethylsilyldiazomethane, and cleavage using amines, provided highly substituted, isomeric pyrazoles 528 and 529 (Scheme 63) <20000L2789>. [Pg.76]
