Asymmetric photochemical reactions in solution

Article Abstract:

The absorption anisotropy (g) factors, while limiting the optical yield (op) in direct asymmetric photoinduction by circularly polarized light (CPL), offers other ways of raising op's. The anomalous two-photon laser excitation, high g transitions of ketones and other compounds, the Cotton effect and careful choice of CPL wavelength and bandwidth are promising routes towards high g factors. Other possible techniques include the use of chemically bonded chiral auxiliaries, chiral complexing agents, tandem photochemical/ thermal reactions and the rotation switching phenomenon at the equipodal temperature.

Absolute asymmetric synthesis under physical fields: facts and fictions

Article Abstract:

Research was conducted to examine the influence of external fields on absolute asymmetric synthesis. Particular emphasis was made on the potential chirality of electric, gravitational and magnetic fields as well as asymmetric photochemistries with polarized protons which constitute a truly chiral influence. Results indicated that true and false chirality is an important criterion for the evaluation of the interaction between matter and an external physical field.
