Preparation and Structure of Oligomeric Iodosylbenzene Sulfate (PhIO)3·SO3: Stable and Water-Soluble Analog of Iodosylbenzene

EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 27 2007
Alexey Y. Koposov
Abstract New phenyliodine(III) sulfate (PhIO)3·SO3, which has a complex polymeric structure of the trimeric iodosylbenzene units linked by sulfate anions, can be conveniently prepared by treatment of (diacetoxy)iodobenzene with sodium bisulfate in the presence of water. This sulfate can find practical application as a readily available, stable, and water-soluble hypervalent iodine reagent with a reactivity pattern similar tothat of iodosylbenzene.

Facile synthesis of N, -protected- l - ,,, -diaminobutyric acids mediated by polymer-supported hypervalent iodine reagent in water

CHEMICAL BIOLOGY & DRUG DESIGN, Issue 2 2004
K. Yamada
Abstract:, Hofmann rearrangement of N, -Boc- l -Gln-OH mediated by a polymer-supported hypervalent iodine reagent poly[(4-diacetoxyiodo)styrene] (PSDIB) in water afforded N, -Boc- l - ,,, -diaminobutyric acid (Boc-Dab-OH, 1) in 87% yield. N, -Z-derivative (Z-Dab-OH, 2) was prepared with PSDIB in 83% yield. Since the reaction of N, -Fmoc-Gln-OH by this procedure did not proceed because of the insolubility of Fmoc-Gln-OH in aqueous media, we synthesized Fmoc-Dab(Boc)-OH (5) from 2 in 54% yield. Polymyxin B heptapeptide (PMBH) which contains four Dab residues was successfully synthesized in a solution-phase synthesis. [source]
