Design, synthesis, molecular docking, antimicrobial, and antioxidant activities of new phenylsulfamoyl carboxylic acids of pharmacological interest
Egbujor, Melford C.,Okoro, Uchechukwu C.,Okafor, Sunday
, p. 2118 - 2127 (2019/11/03)
The research explores the facile synthesis of some new phenylsulfamoyl carboxylic acids, their molecular docking, antimicrobial, and antioxidant activities. The procedure involved the mild reaction of amino acids with benzenesulfonyl chloride in a medium

scheme or table, p. 828 - 835 (2012/02/03)
New chiral aminoamidoximes were prepared from (L)-proline, (L)-alanine, and (L)-isoleucine by treatment of the corresponding aminonitriles with hydroxylamine in the presence of triethylamine. The intramolecular cyclization with α-bromoacid chlorides and aldehydes was investigated to give new 1,2,4-oxadiazin-6-ones and 1,2,4-oxadiazoles, respectively. These compounds were likely to undergo an intermolecular cyclization through oxygen and nitrogen. However, intramolecular cyclization through two nitrogens did not occur even after changing reaction conditions. Taylor & Francis Group, LLC.

Structure-based design and synthesis of potent matrix metalloproteinase inhibitors derived from a 6H-1,3,4-thiadiazine scaffold

, p. 3231 - 3243 (2007/10/03)
We describe a new generation of heterocyclic nonpeptide matrix metalloproteinase (MMP) inhibitors derived from a 6H-1,3,4-thiadiazine scaffold. A screening effort was utilized to identify some chiral 6-methyl-1,3,4-thiadiazines that are weak inhibitors of
α-Amino Acids as Chiral Educts for Asymmetric Products. The Synthesis of α'-Amino-α,β-ynones
Cupps, Thomas L.,Boutin, Raymond H.,Rapoport, Henry
, p. 3972 - 3979 (2007/10/02)
α-Amino acid isoxazolidides have been developed as educts for the preparation of optically pure α'-amino-α,β-ynones.The α-amino acids were first N-protected as their ethoxycarbonyl, tert-butoxycarbonyl, or phenylsulfonyl derivatives.The isoxazolidides then were formed by the simple, high yield acylation of isoxazolidine by in situ generated α-amino acid isobutyl carbonic anhydrides.Individual isoxazolidides of L-α-N-substituted alanine, phenylalanine, and methionine, when treated with lithium acetylide, lithium (trimethylsilyl)acetylide, or 1-hexynyllithium, gave high yields of the corresponding optically pure α,β-acetylenic ketones.
α-Amino Acids as Chiral Educts for Asymmetric Products. Amino Acylation with N-Acylamino Acids
Buckley, Thomas F.,Rapoport, Henry
, p. 6157 - 6163 (2007/10/02)
α-N-Acylamino acids have been developed as useful reagents for the preparation of optically pure α-aminoalkylaryl ketones.Protection of the amino group as either the ethoxycarbonyl or benzenesulfonyl derivative allows alanine to serve as an effective educt for the chirally specific synthesis of a variety of structures containing the phenylethylamine backbone.Benzene undergoes Friedel-Crafts acylation with the N-acylalanine acid chloride.Catalyst complexation with oxagenated aromatics, however, prohibits acylation of aryl ethers.An arylmetallo reaction scheme overcomes this problem and also affords regiospecificity not attainable in conventional acylations.As examples, optically pure ephedrines and amphetamines were directly synthesized without recourse to resolution since the chirality of the amino acid educt was entirely conserved throughout the process.
