A highly enantioselective amino acid-catalyzed route to functionalized alpha-amino acids.
The development of syntheses providing enantiomerically pure alpha-amino acids has intrigued generations of chemists and been the subject of intense research. This report describes a general approach to functionalized alpha-amino acids based on catalytic asymmetric synthesis. Proline catalyzed Mannich-type reactions of N-PMP-protected alpha-imino ethyl glyoxylate with a variety of unmodified ke...
متن کاملThe Use of WMethylation to Direct the Route of Mediated Transport of Amino Acids*
Inhibition analysis and the study of interactions for countertransport indicate that for the Ehrlich cell (1) and for the mammalian erythrocyte (2) (and apparently also for intestinal and renal transport, as discussed elsewhere (I)), the neutral amino acids share a small number of distinct broad affinity transport systems. Recently, evidence pointing in somewhat the same direction for slices of...
متن کاملThe use of topological indices to predict thermodynamic properties of amino acids derivatives
In the present investigation the applicability of various topological indices are tested for the QSPR study on 80 amino acids derivatives. Relationship between the Randic' (1X), Balaban (J), Szeged (Sz), Harary (H), Wiener (W), Hyper-Wiener (WW) and Wiener Polarity (WP) indices to the thermodynamic Properties such as thermal energy Eth (J/mol) and heat capacity (CV J/mol. K) of amino acids is r...
متن کاملa synchronic and diachronic approach to the change route of address terms in the two recent centuries of persian language
terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
15 صفحه اولRuthenium-catalyzed aerobic oxidative decarboxylation of amino acids: a green, zero-waste route to biobased nitriles.
Oxidative decarboxylation of amino acids into nitriles was performed using molecular oxygen as terminal oxidant and a heterogeneous ruthenium hydroxide-based catalyst. A range of amino acids was oxidized in very good yield, using water as the solvent.
