Aiming at establishing the spatial arrangement of the oximes the hydrolysis was carried out of acid amides obtained by Beckmann rearrangement of oximes of methyl ketones belonging to unsaturated 脦鲁-lactone series and also to aromatic and alicyclic series. The hydrolysis with 20% sulfuric acid led...

The acid-catalyzed hydrolysis of a series of six 2,4-dichlorophenyl methyl N-alkylphosphoramidates (I) has been studied. Most of the reactions were carried out in 25% dioxane in water (v/v) in the presence of 0.19 M HCl, with the concentration of phosphoramidate being 0.002 M. The ...

First, the amino acid composition is determined after acid hydrolysis. The procedure (separation on a single cation exchange resin column and color development with ninhydrin reagent) has been standardized and automated (amino acid analyzers). More recently, derivatization of amino acids to form ...
The greater reactivity of esters relative to amides has typically been reflected in their faster rates of both solvolysis and enzymatic hydrolysis. In contrast to this general principle, the serine hydrolytic enzyme fatty acid amide hydrolase (FAAH) was found to degrade amides and esters with equival...
Pronase-catalysed hydrolysis of amino acid amidesPronasehydrolysisamino acid amidesPronase from Streptomyces griseus exhibits a high activity and enantioselectivity in the hydrolysis of three amino acid amides: leucine amide, phenylalanine amide and tryptophan amide.
