15 صفحه اولSynthesis and Protein Incorporation of Azido-Modified Unnatural Amino Acids.
Two new azidophenylalanine residues (3 and 4) have been synthesized and, in combination with 4-azido-L-phenylalanine (1) and 4-azidomethyl-L-phenylalanine (2), form a series of unnatural amino acids (UAAs) containing the azide vibrational reporter at varying distances from the aromatic ring of phenylalanine. These UAAs were designed to probe protein hydration with high spatial resolution by uti...
متن کاملVisible-light photoredox synthesis of unnatural chiral α-amino acids
Unnatural chiral α-amino acids are widely used in fields of organic chemistry, biochemistry and medicinal chemistry, and their synthesis has attracted extensive attention. Although the asymmetric synthesis provides some efficient protocols, noble and elaborate catalysts, ligands and additives are usually required which leads to high cost. Distinctly, it is attractive to make unnatural chiral α-...
متن کاملA modular synthesis of dithiocarbamate pendant unnatural α-amino acids.
Unnatural α-amino acids containing dithiocarbamate side chains were synthesized by a one-pot reaction of in situ generated dithiocarbamate anions with sulfamidates. A wide range of these anions participated in the highly regio- and stereo-selective ring opening of sulfamidates to produce the corresponding dithiocarbamate pendant α-amino acids in high yields.
متن کاملEnolboration of conjugated ketones and synthesis of b - amino alcohols and boronated a - amino acids *
Enolization–aldolization of conjugated ketones, enantioselective synthesis of benzofuryl β-amino alcohols, and synthesis of p-dihydroxyborylphenylalanine (BPA) and its analogs are described. Aldolization of benzaldehyde with lithium dienolates derived from unhindered conjugated cyclohexenones favored anti selectivity, whereas syn selectivity was favored for hindered cyclohexenones. Anti-aldols ...
