Aryloxide‐Facilitated Catalyst Turnover in Enantioselective α,β‐Unsaturated Acyl Ammonium Catalysis
A new general concept for α,β-unsaturated acyl ammonium catalysis is reported that uses p-nitrophenoxide release from an α,β-unsaturated p-nitrophenyl ester substrate to facilitate catalyst turnover. This method was used for the enantioselective isothiourea-catalyzed Michael addition of nitroalkanes to α,β-unsaturated p-nitrophenyl esters in generally good yield and with excellent enantioselect...
متن کاملUpdate on Reactive Oxygen Species in Plant Pathology Reactive Oxygen Species Signaling in Response to Pathogens
The production of reactive oxygen species (ROS), via consumption of oxygen in a so-called oxidative burst, is one of the earliest cellular responses following successful pathogen recognition. Apoplastic generation of superoxide (O2 ), or its dismutation product hydrogen peroxide (H2O2), has been documented following recognition of a variety of pathogens (Doke, 1983; Auh and Murphy, 1995; Grant ...
متن کاملUpdate on Reactive Oxygen Species in Plant Cell Death Reactive Oxygen Species in Plant Cell Death
Paradoxically, death is an integral part of life. Cell death is essential for growth and development of eukaryotes, by maintaining tissue and organ homeostasis in concert with cell proliferation, growth, and differentiation. Until recently, the wide variety of cell death types reported in the literature was mostly caged in two semantic categories: apoptosis and necrosis. Discrimination between ...

This over-all equation is thought to consist of the repetition of a series of reactions, each series being initiated by the condensation of malonyl coenzyme A with an unsubstituted straight chain acyl compound to form ,&ketoacyl-S-enzyme (5, 8). A series is then presumably concluded by reactions in which the P-ketoacyl compound is reduced and dehydrated to form an acyl compound 2 carbon atoms l...

shown by demonstrating that the overall rate of dextransucrase synthesis is independent of the concentration of 1,6-linked dextran acceptor if synthesis is continued for periods that are directly proportional to the amount of acceptor present. For example, in the presence of 1 mg of acceptor dextran, the rate of dextransucrase action measured over lOmin is identical with the rate measured over ...
