Studies of catalysis of the hydrolysis of phenyl glycinate and some related esters
… esters. Some data on 4-methoxyphenyl glycinate are also reported, together with some new data on 4-nitrophenyl esters required for comparison purposes. Studies have concentrated on catalysts previously reported as effective in the hydrolysis of 4-nitrophenyl esters of amino acids, the …

First principles theory of organic molecules on metal surfaces : formate, 3-thiophene-carboxylate and glycinate on Cu(110)
… 3-thiophene carboxylate (planar molecules) and glycinate (3-dimensional structure). Formate molecule: Several geometries corresponding to low and high coverages of formate molecules in a (2x2) unit cell on clean and oxygen-precovered Cu surface have been optimized. For all configurations we …

Mathematical modeling and simulation of the performance of potassium glycinate in CO2 absorption in a packed-bed absorption column
… for the capture of CO2 using potassium glycinate as the absorption solvent. To this end, the study was subdivided into three major parts each designed to generate the requisite data for the subsequent stage. The three major parts of the study included the development of industrial …

The asymmetric synthesis of (2S,3R)-capreomycidine and the total synthesis of capreomycin IB
… aluminum enolate-aldimine reaction with a chiral glycinate, which sets both stereocenters. A concise and high-yielding approach to the unnatural amino acid (2S,3S)-β-hydroxyornithine is also reported. The key step in this approach is a boron-mediated aldol reaction with a chiral glycinate. …

Development of solvent for CO2 capture for utilization in concrete and storage in geological formations
… for potassium lysinate salt, KOH, and potassium glycinate salts respectively. Moreover, the optimum absorption condition for the best-performing solvents were experimentally determined to be 3M and 40oC, 5M and 60oC, and 6M and 60oC for aqueous potassium lysinate salt, KOH and potassium glycinate …

Chemical modification of catalytically essential functional groups in the active site of papain
… ethyl ester resulted in incorporation of 6 ethyl glycinate residues per molecule of enzyme, with essentially complete inactivation. In the presence of benzamidoacetonitrile, a competitive inhibitor of papain, only four ethyl glycinate residues were incorporated into active papain with retention of …

The asymmetric synthesis of amino acids via electrophilic glycinates
… of 108 with NBS generates the key electrophilic glycinate 132 which couples with a variety of carbon nucleophiles with high diastereoselectivity to afford the amino acid precursors 134. Catalytic hydrogenation of homologated heterocycles 134 directly furnishes the zwitterionic α-amino acids in …

Induced pi-facial discrimination in the alkylation of chiral derivatives of glycine.
… of the trans 2-phenylcyclohexylamide of methyl glycinate with a series of electrophiles was examined. Incorporation of the chiral auxiliary on the amino terminus of the amino acid appears to induce good stereoselectivity only when the electrophiles contain a point of unsaturation. The reaction …

Greener Surface Active Reagents: Structure, Property and Performance Relationships
… lauroyl sarcosinate (C12Sar), and sodium lauroyl glycinate (C12Gly), were tested as triblend mixtures with dodecyl glucoside (C12G1) and lauramidoproply betaine (LAPB) to evaluate their performance as a function of their molecular structures. The C12Gly/C13G1/LAPB system was confirmed to have very …

Analytical separations using packed and open-tubular capillary electrochromatography
… cationic polymer and poly (sodium N-undecanoyl-L-glycinate), poly (L-SUG), was used as the anionic polymer for the construction of the PEM coating. The performance of the modified capillaries as a separation medium was evaluated by use of seven benzodiazepines as analytes. In the second study, the …
