The investigations presented in this thesis set out to expand asymmetric diarylmethane synthesis beyond the constraints of redox pre-activated substrates, steric bias, and electronic differentiation. Guided by the mechanistic blueprint proposed by PARK et al. and inspired by constitutional stereodivergence concepts developed by CHIRIK and co-workers, we aimed to establish an enantioconvergent platform that strategically exploits stereoablation as key step to generate chiral diarylmethanes from readily accessible stilbenes. By addressing each of the critical questions formulated in the Objectives (see Chapter 2), this work provides a comprehensive conceptual and experimental foundation for a new class of stereocontrolled reconstitutive oxygenation reactions enabled by photoredox selenium-π-acid dual catalysis.
