RESUMO
[reaction: see text] New amino acid-derived iodobenzene dicarboxylates were prepared by the reaction of (diacetoxyiodo)benzene with N-protected natural amino acids. These compounds in the presence of iodide anion can be used as reagents for beta-iodocarboxylation of alkenes leading to the respective amino acid esters.

RESUMO
New N-functionalized benziodazoles were prepared by the peracetic oxidation of 2-iodobenzamides derived from alanine or valine. X-ray crystal structural analysis of two benziodazole-based phenyliodonium derivatives provides insight into facile interchange between benziodazoles and iminium benziodoxoles under acidic or basic conditions.
