A Mild and Chemoselective Reduction of Cyclic Iminium Salts
No full textN-Substituted cyclic iminium salts are conveniently reduced to the corresponding tertiary amines in good yields by reaction with tributylstannane in methanol at room temperature. A variety of functional groups (such as ketonic groups) present in the molecule are not affected under these conditions
Asymmetric biomimetic oxidations of phenols: the mechanism of the diastereo- and enantioselective synthesis of dehydrodiconiferyl ferulate (DDP) and dehydrodiconiferyl alcohol (DDA)
No full textStereoselective bimolecular radical coupling of enantiopure phenylpropenoidic phenols are described, starting from enantiopure amidic derivatives of ferulic acid. The latter were prepared from ferulic acid by reaction with (S)-alanine or Oppolzer camphor sultam. The oxidation step was performed both enzymatically (HRP/H2O2) and chemically (Ag2O). The observed enantioselectivity in the oxidation step encompasses the range 65-84% and is consistent with the conformational analysis of the quinone methide intermediates at the PM3 level.

Travel Time Forecasting and Dynamic Routes Design for Emergency Vehicles
No full textAbstractA framework to dynamically design routes of emergency vehicles taking into account within-day variations of link travel times on a road network is presented. The framework integrates two modelling components: (i) a within-day dynamic assignment model that simulates the interaction between the time-varying network and travel demand, and (ii) a dynamic vehicle routing model that design optimal routes of emergency vehicles. The linking variable of the two modelling components is the short-term forecasted travel time, which allows to design routes of emergency vehicles based on anticipatory knowledge of traffic dynamics on the road network. Some procedures of the proposed framework are calibrated and validated in an experimental evacuation test site
