Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

Chemistry – A European Journal, EarlyView.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Dearomatization with Axial‐to‐Central Chirality Conversion

European Journal of Organic Chemistry, EarlyView.
Atropisomers are exciting synthetic targets with unique properties, which find applications in many fields of chemistry. However, considering them as substrates is not very frequent, notably in the context of dearomatization reaction. We wish to discuss the different strategies for the dearomatization of aromatic atropisomers with axial‐to‐central ...

Consumption of antibiotics at St Luke’s Hospital : a critical factor behind the local prevalence of antimicrobial resistance? [PDF]

, 2006
The intensity of antibiotic use in hospital settings is recognised as possibly the most important factor for the selection of antimicrobial resistance. Hospitals are therefore being encouraged to undertake surveillance and benchmarking of antimicrobial ...
