Toxicity of Certain Chemical Compounds Against Aphids, Leafhoppers AND Related Predators on Faba Bean Fields [PDF]
Journal of Plant Protection and PathologyFaba bean, Vicia faba L., is a main nutritive source for human beings and their domestic animals. Many insect pests have been recorded on Vicia faba such as aphids, leafhoppers which are the most harmful insects, causing a considerable loss in yield ...

Z‐Retentive Enantioselective Rh‐Catalyzed Hydroarylation of E,Z‐Dienes
Angewandte Chemie, EarlyView.The Rh‐catalyzed hydroarylation of conjugated E,Z‐dienoates is found to proceed with high selectivity for addition to the E‐alkene unit. Mechanistic analysis of this Z‐retentive process points towards preferred binding of the E‐alkene unit to a Rh‐aryl species to give rise to the observed selectivity and that Rh‐enolate protonolysis to be turnover ...

Benzothiazole carbamates and amides as antiproliferative species [PDF]
, 2018 A series of new benzothiazole-based carbamates and amides were synthesized and their antiproliferative activity was determined. Derivatives with profound activity were identified and further investigated for their possible mechanism of action.

Angewandte Chemie, EarlyView.The first nitrile reductive couplings beyond stoichiometric metals or metalloids are described. Using a ruthenium catalyst derived from RuHCl(CO)(PPh3)3 and Cy‐BIPHEP, 2‐propanol‐mediated reductive coupling of phenyl acrylate with aromatic or aliphatic nitriles delivers α,β‐unsaturated β‐amino esters.

Carbamates as Potential Prodrugs and a New Warhead for HDAC Inhibition
Molecules, 2018 We designed and synthesized carbamates of the clinically-approved HDAC (histone deacetylase) inhibitor vorinostat (suberoylanilide hydroxamic acid, SAHA) in order to validate our previously-proposed hypothesis that these carbamates might serve as ...

Practical Synthesis of Unsymmetrical Ureas from Isopropenyl Carbamates
, 2016 A very convenient method for the synthesis of unsymmetrical ureas is described, based on isopropenyl carbamates. The synthetic efficiency of traditional methods for urea formation, such as use of phosgene or alkyl and aryl carbamates, is limited by the ...
