Recent Trends in Photocatalytic Enantioselective Reactions.

Enantioselective synthesis through photocatalysis is one of the highly preferred approaches towards preparation of optically active compounds. This review elaborates and critically analyzes the different strategies of photocatalytic enantioselective reactions through H-bonding, transition metal catalysis, phase-transfer catalysis (PTC), chiral Lewis acid catalysis, N-heterocyclic carbene catalysis, and amine catalysis, and also explores ion pairs. In addition, it explains the different catalysis modes with multifunctional approaches for enantioselective photocatalytic reactions.
