Greener and sustainable method for alkene epoxidations by polymer-supported Mo(VI) catalysts [PDF]
A polybenzimidazole supported Mo(VI) (PBI.Mo) catalyst has been prepared and characterised. The catalytic activities of the PBI.Mo catalyst in epoxidation of alkenes with tert-butyl hydroperoxide (TBHP) as an oxidant have been studied under different ...

Ring-opening copolymerization (ROCOP): synthesis and properties of polyesters and polycarbonates [PDF]
Controlled routes to prepare polyesters and polycarbonates are of interest due to the widespread application of these materials and the opportunities provided to prepare new copolymers. Furthermore, ring-opening copolymerization may enable new poly(ester–

2,6-exo-8,10-exo-4-Butyl-9-oxa-4-azatetracyclo[5.3.1.02,6.08,10]undecane-3,5-dione
The title epoxide was obtained by spontaneous epoxidation of the corresponding unsaturated imide in air or by peracid oxidation. Unambiguous assignment of the 1H- and 13C-NMR spectra is achieved by comparison between analogous compounds and its X-ray ...

Soluble Epoxide Hydrolase Inhibition for Ocular Diseases: Vision for the Future [PDF]
Ocular diseases cause visual impairment and blindness, imposing a devastating impact on quality of life and a substantial societal economic burden. Many such diseases lack universally effective pharmacotherapies.

Ab-initio transport fingerprints for resonant scattering in graphene [PDF]
We have recently shown that by using a scaling approach for randomly distributed topological defects in graphene, reliable estimates for transmission properties of macroscopic samples can be calculated based even on single-defect calculations [A. Uppstu et al., Phys. Rev. B 85, 041401 (2012)].

Catalytic Annulation of Epoxides with Heterocumulenes by the Indium-Tin System
In the synthesis of five-membered heterocycles by the annulation of epoxides with heterocumulenes such as carbon dioxide and isocyanates, we developed the indium-tin catalytic system and synthesized various cyclic adducts including novel types products ...

Enantioselective Synthesis of 5-epi-Citreoviral Using Ruthenium-Catalyzed Asymmetric Ring-Closing Metathesis [PDF]
Chiral ruthenium olefin metathesis catalysts can perform asymmetric ring-closing reactions in ≥90% ee with low catalyst loadings. To illustrate the practicality of these reactions and the products they form, an enantioselective total synthesis of 5-epi ...
