compatible with sensitive environments. Applications in bioconjugation and cellular mapping further reflect the breadth and impact that this renaissance continues to enjoy across the scientific landscape. Whilst this success highlights the effectiveness of photocatalysis in forging new bonds, the non-covalent nature of activation, coupled with the high reactivity of the intermediates that are generated, render enantiocontrol a conspicuous challenge (Figure ). An expansive solution has proven to be dual-catalysis; a regime in which the photocatalyst operates in concert with an established ground-state chiral catalysis manifold. Enantioselective bond-forming events typically occur from a secondary photoreaction involving a light-generated intermediate. In contrast, processes that leverage chiral photocatalysts to directly confer enantioselectivity are conspicuously under-represented: this accentuates the challenges associated with identifying and developing "privileged chiral photocatalysts". Seminal work by Bach and co-workers has established the effectiveness of lactam-based scaffolds, derived from Kemp´s triacid, in orchestrating enantioselection in photochemical processes: this blueprint emulates biological recognition in which complementary hydrogen bonding motifs in the catalyst and substrate ensure structural pre-organization. The modularity of this venerable organocatalyst chromophore can be tuned to enable both enantioselective energy-transfer (EnT) and single electron transfer (SET) processes for substrates bearing a suitable amide group. Substrate-based recognition motifs have also been successfully leveraged in the development of chiral, Ir(III) complexes for enantioselective photocatalysis. Elegant studies by Meggers and co-workers have established that acyl imidazole substrates engage with chiral Ir(III) Lewis acids to enable direct, visible-light-induced asymmetric redox catalysis processes. The importance of precision hydrogen bonding motifs in this context has also been convincingly demonstrated by Yoon, Baik and co-workers to enable enantioselective excited-state photoreactions controlled by a chiral hydrogen-bonding iridium sensitizer. Collectively, these milestones show that remarkable levels of enantio-induction can be achieved under the auspices of a single, chiral photocatalyst when complementary (H-bonding) recognition motifs are present. Expanding this paradigm to include substrates bearing common functional groups for recognition is highly appealing and would ultimately lead to the identification of privileged chiral photocatalysts. However, the nexus of this endeavor is identifying ground state recognition modes that can be replicated in an excited state paradigm. This led us to explore the strong oxophilicity of earth-abundant aluminum in creating a Lewis acid-Lewis base component of an emerging chiral blueprint (Fig. ). Further confidence in this key interaction stemmed from the well-established photochemistry of aryl ketones, particularly under Lewis acid activation. Motivated by their success in ground state catalytic processes, chiral Al-salen catalysts were identified as attractive candidates to regulate primary and secondary photoreactions. A combination of Lewis acidity, a privileged chiral ligand sphere and well-defined optical properties render Al salen complexes promising candidates to expand the existing chiral photocatalyst portfolio. To validate the concept of salen photocatalysis, the deracemization of cyclopropanes was conceived (Fig. ): this stemmed from our group´s interest in photocatalytic alkene isomerization, the reactivity parallels between olefin π-systems and cyclopropyl Walsh orbitals, and the historic challenges associated with achieving induction as exemplified by the seminal work of Hammond and Roussi . The ability to activate cyclopropanes through adjacent low-lying antibonding orbitals rendered cyclopropyl ketones particularly attractive as substrates for this endeavor. The transformation would contribute to the growing interest in light-enabled deracemization of small molecules using low molecular weight photocatalysts. To this growing repertoire, it was envisaged that chiral aluminum salen complexes could be effectively utilized in the deracemization of cyclopropyl ketones through electron-transfer to the carbonyl group: this would be achieved through substrate coordination and subsequent excitation of the ligand chromophore, followed by electron-transfer in a chiral environment (Fig. ).
