Bioinspired Synthesis of Twin abeo‐Steroids Bufogargarizins A and B via a Divergent Intramolecular Aldol Addition Reaction

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Twin natural products. This manuscript describes a concise biomimetic synthesis of twin abeo‐steroids bufogargarizins A and B with an unusual [7.5.6.5] and [5.7.6.5] skeletons in 19 steps (LLS). The described synthetic approach features the application of a bioinspired regiodivergent intramolecular aldol addition reaction and a selective singlet oxygen‐

Bright Circularly Polarized Electrochemiluminescence from Heterobinuclear IrIII–AuI Enantiomers

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Efficient and bright circularly polarized electrochemiluminescence (CP‐ECL) is achieved in a class of enantiopure hetobinuclear iridium(III)–gold(I) complexes owing to the combination of high ECL efficiency with stability, good emission dissymmetry factor and high brightness, thus paving the way to the next‐generation of bright CP‐ECL probes.
