N-Cinnamoyl-l-phenylalanine methyl ester
As part of an ongoing investigation into the development of N-substituted amino acids as building blocks for dynamic combinatorial chemistry, we report the structure of the title compound, C(19)H(19)NO(3). This compound crystallizes as discrete mol-ecules. The cinnamoyl group is non-planar, with the phenyl ring and the amide twisted out of the ethyl-ene plane. The benzyl and ester groups lie ab...
متن کاملChemical modification of ribonucleic acid polymerase with N-bromosuccinimide.
The mechanism of specific interaction between a protein and a nucleic acid is thought to reside partially in the arrangement and types of amino acid present in the protein. Attempts have been made to assign specific roles in this interaction to certain amino acids, for example, tryptophan and tyrosine are thought to be involved in unwinding the double helix of DNA (Brun et al., 1975), and in se...
متن کاملProbing the reactivity of o-phthalaldehydic acid/methyl ester: synthesis of N-isoindolinones and 3-arylaminophthalides.
A new method for the synthesis of N-substituted isoindolinones and 3-arylaminophthalides was developed through aza-Wittig/cyclisation. The reaction of o-phthalaldehydic acid methyl ester with benzylic, aromatic and aliphatic azides gave N-isoindolinones whereas reaction of o-phthalaldehydic acid with the aromatic azides gave 3-arylaminophthalides.
متن کاملSpectrophotometric Determination of Pantoprazole Sodium in Pharmaceuticals Using N-Bromosuccinimide, Methyl Orange and Indigo Carmine as Reagents
Two sensitive spectrophotometric methods are presented for the assay of pantoprazole sodium sesqui hydrate (PNT) in bulk drug and in formulations using N-bromosuccinimide (NBS) and two dyes, methyl orange and indigo carmine, as reagents. The methods involve the addition of a known excess of NBS to PNT in acid medium, followed by determination of unreacted oxidant by reacting with a fixed a...
متن کاملN-{N-[N-(1,1-Dimethylethoxycarbonyl)-l-leucyl]-N-methyl-l-leucyl}-N-methyl-l-leucine benzyl ester
The tripeptide title compound, C(32)H(53)N(3)O(6), synthesized in 80% yield by coupling of N-methyl-l-leucine benzyl ester with tert-butoxy-carbonyl-l-leucyl-N-methyl-l-leucine at 273 K, conjugates through two amide linkages and includes two protecting groups: a tert-butyl-oxycarbonyl group at the C-tip and a benzyl group at the N-tip. A classical inter-molecular N-H⋯O hydrogen bond and a weak ...
