Photocatalyst‐Free Trifluoromethylation of Indolizines Through an Electron Donor–Acceptor Complex
European Journal of Organic Chemistry, EarlyView.A new photocatalyst‐free pathway for the direct C‐3‐trifluoromethylation of indolizines and imidazo[1,2‐a]pyridines through an electron donor–acceptor (EDA) complex is studied. This regioselective reaction supports a wide range of functional groups, indicating good versatility and robustness.

Photocatalysis‐Triggered Click Reactions and Applications
European Journal of Organic Chemistry, EarlyView.Photoclick chemistry offers broad applications ranging from materials science to bioconjugation, with precise spatiotemporal control over click reactions. Initially limited to UV activation, recent advances have extended photoclick processes to the visible and NIR regions thanks to the photocatalysis.

This chapter deals with enantioselective organocatalytic cycloaddition reactions. Several cinchona alkaloids have been recently demonstrated as efficient chiral organocatalysts for enantioselective Diels−Alder reactions. Thus, excellent results were obtained for the Diels−Alder reaction of 3-vinylindoles with maleimides catalysed by a ...

This chapter considers cycloadditions as the most useful of all pericyclic reactions in organic synthesis. It describes the wide range of known cycloadditions, identifies the conditions under which they take place, draws attention to their regio- and stereochemistry, and gives the simple rules for which of them take place and which do not.

Selectivity in an Encapsulated Cycloaddition Reaction
Organic Letters, 2002A 1,3-dipolar cycloaddition takes place within a reversibly formed, self-assembled capsule. The reaction proceeds through an unsymmetrically loaded encapsulation complex with absolute regioselectivity.
