Abstract:
Recently, hypervalent iodine reagents have been extensively used in organic synthesis. A variety of reactions available for natural product syntheses have been developed using phenyliodine(III) diacetate (PIDA), phenyliodine(III) bis(trifluoroacetate) (PIFA), and other iodine(III) and (V) reagents. These reactions are expected to have applications in pharmaceutical and agrochemical processes because of their safety, mild reaction conditions, and high yields of pure products. Under such considerations, this chapter focuses on the oxidative coupling reactions of hypervalent iodine reagents found in total syntheses of biologically active natural products and their related compounds.
