Triplet Energy Transfer from Ruthenium Complexes to Chiral Eniminium Ions: Enantioselective Synthesis of Cyclobutanecarbaldehydes by [2+2] Photocycloaddition Alexander von Humboldt

Triplet Energy Transfer from Ruthenium Complexes to Chiral Eniminium Ions: Enantioselective Synthesis of Cyclobutanecarbaldehydes by [2+2] Photocycloaddition

Introduction The electronic properties of olefins that are conjugated with a carbonyl group are altered by modifications at the carbonyl group. In this context, the formation of eniminium ions from α,β‐unsaturated aldehydes has had a major impact on the development of organocatalytic reactions.1 Kindled by the pioneering studies of MacMillan…

The COVID-19 pandemic and disparate international response to the deadly virus has put diplomacy on a standstill. International organizations, including the United Nations, have virtually shuttered their offices. Bilateral engagements have also dwindled amid travel restrictions and countries turn their attentions inward to managing the Corona virus. Perhaps one exception…
