Considerable evidence exists that the carboxyl-carbon atom of glycolic acid is the primary source of the CO(2) produced during photorespiration by leaves of many species of plants, including tobacco. Experiments were conducted to determine whether glyoxylate or glycine, both products of glycolic acid metabolism, is the more immediate precursor of photorespiratory CO(2).Illuminated tobacco leaf ...
Methane is abundant and relatively inexpensive, making it an attractive feedstock for producing bulk chemicals. However, the low reactivity of methane makes it difficult to develop commercially viable processes for methane conversion. Because of favorable thermodynamics, many authors have investigated the oxidation and oxidative carbonylation of methane. By contrast, the sulfonation of methane ...
New pincer ruthenium complexes, [Ru(SCS)(tpy)]PF(6) (1) (SCS = 2,6-bis(benzylaminothiocarbonyl)phenyl), tpy = 2,2':6',2''-terpyridyl) and [Ru(SNS)(tpy)]PF(6) (2) (SNS = 2,5-bis(benzylaminothiocarbonyl)pyrrolyl), having κ(3)SCS and κ(3)SNS pincer ligands with two secondary thioamide units were synthesized by the reactions of [RuCl(3)(tpy)] with N,N'-dibenzyl-1,3-benzenedicarbothioamide (L1) and ...
An in-house developed automated synthesis suite was used to prepare a library of 72 tetrapeptide derivatives, the starting materials for pharmaceutically attractive pentapeptides, employing a convergent strategy. An initial set of 18 dipeptides were synthesized on a large-scale (100-1000 g) using automated synthesis workstations, and then 72 tetrapeptides were synthesized on a medium scale (5-1...
