Enantioselective [2+2] Cross-Photocycloaddition Enabled by a Chiral Cage Reactor via Multilevel-Selectivity Control

ACS Catalysis, Год журнала: 2024, Номер 14(10), С. 7321 - 7331

Опубликована: Апрель 25, 2024

In the recently burgeoning field of asymmetric [2 + 2] photocycloaddition, a challenging hurdle lies in achieving multilevel control chemo-, regio-, diastereo-, and enantioselectivities cross-coupling photoreactions, which often result chaotic outcomes when partners show similar electronic optical properties. Here, we introduce biomimetic cage-pocket confined photocatalytic protocol that can effectively realize bimolecular recognition manipulate excited triplet-state dynamics through stereochemical confinement. This approach allows for highly selective synthesis heterocoupled syn-HH (head-to-head) enantiomers from two photoactive α,β-unsaturated carbonyl compounds, are typically difficult to access via conventional strategies due competitive pathways. We find cooperative heteromolecular binding plays critical role initial chemoselective successive stereoselective photoreactions. Notably, open pockets cage reactor display tolerable guest–host match but products–host mismatch wide scope substrates, overcoming common limitations associated with enzyme-mimicking reactors such as guest specificity product inhibition against catalytic generality turnover.
