experimental part, p. 704 - 711 (2009/04/10)
Various conjugates of amino acids with chrysin in which the amino acid was bonded through the C- or N-terminus to the flavone were prepared using peptide chemistry methods (symmetric anhydrides and activated esters).
Amino acid derivatives of 2-R-7-hydroxy-3',4'-ethylenedioxyisoflavones

A number of 7-O-aminoacyl derivatives of isoflavones have been obtained by the interaction of 2-R-7-hydroxy-3′,4′-ethylenedioxyisoflavones with the symmetrical anhydrides of N-protected amino acids.

Using 32.4 MHz (31)P n.m.r. spectroscopy, disproportionation of a series of phosphinic carboxylic mixed anhydrides derived from protected α-amino acids has been studied both as a function of the substituents at phosphorus and structure of the α-amino acid being activated.It was found that the rates of disproportionation were insignificant from a preparative aspect compared with aminolysis at 0 deg C.
ACTIVATION OF A CARBOXY GROUP BY DIALKYL PYROCARBONATES. SYNTHESIS OF SYMMETRICAL ANHYDRIDES AND ARYL ESTERS OF N-PROTECTED AMINO ACIDS USING DI-tert-BUTYL PYROCARBONATE AS CONDENSING REAGENT
Pozdnev, V. F.,Chernaya, M. Yu.
, p. 333 - 337 (2007/10/02)
It has been shown that di-tert-butyl pyrocarbonate can be used as a condensing reagent in the production of anhydrides and some aryl esters of carboxylic acids.The synthesis of anhydrides and of phenyl, p-nitrophenyl, β-naphtyl, and quinolin-8-yl esters of N-protected amino acids is described.
