Photoinduced-electron-transfer chemistry: From studies on PET processes to applications in natural product synthesis

Article Abstract:

The use of photoinduced electron transfer (PET) to the carbonyl chromophore as an important step in heterocycle synthesis is presented. Starting from simple substrates ,electronically excited carbonyl components can oxidize amines, thioethers, and carboxylates generating radical ion pairs that can undergo a series of secondary reactions leading to very interesting nitrogen-containing natural heterocycles.

Supramolecular systems as microreactors: control of product selectivity in organic phototransformation

Article Abstract:

Research suggests that the molecular photochemical reactions of orgnic compounds in microreactors and solution differ with the latter deviating with respect to product distribution. This microreactor-controlled selectivity in organic phototransformation can be employed to enhance asymmetric induction in enantioselective photochemical reactions.

Reflection on medium effects on photochemical reactivity

Article Abstract:

A modified view on rhodopsin photoisomerization is presented along with the consideration that confinement does not necessarily lead to inhibition of reactions of the trapped substrate. The effects of host molecules on photochemical reactivity of trapped molecules are examined.
