Epoxidation of Cashmeran and Unprecedented Rearrangement to an α‐Carbonyl δ‐Spirolactone

European Journal of Organic Chemistry, Volume 29, Issue 28, 25 July 2026.
A new strategy enables diastereoselective conversion of Cashmeran into a previously unknown α‐carbonyl δ‐spirolactone via epoxidation, Baeyer–Villiger oxidation, and acid‐catalyzed rearrangement. Structure and mechanism were confirmed by NMR, single crystal X‐ray diffraction, and computational studies. We report the epoxidation of Cashmeran followed by

Reenvisioning the De Mayo Reaction: A Boron‐Enabled Cycloaddition Approach

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
An oxa‐boracycle conformational lock strategy enables photocatalytic [2+2] cycloaddition to afford densely substituted cyclobutylboronates. The conformational constraint suppresses triplet relaxation and promotes productive bimolecular reactivity.

Synthesis of Benzopyran Atropisomers via Electrophilic Halogenation

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
We report a halogenation‐based method for the synthesis of axially chiral benzopyrans, tolerating diverse substituents and halogens (Br, Cl, and I). A double bromination gives bisbenzopyrans with two stereogenic axes. Preliminary enantioselective conditions yield benzopyran atropisomer with up to 56% ee.

Total Synthesis of Sacrolide A and Cytotoxic Evaluation

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
Isolated from the edible cyanobacterium Aphanothece sacrum, sacrolide A is a highly potent antimicrobial and cytotoxic metabolite. Its total synthesis via a convergent strategy enabled accurate assessment of its effects on liver and colon cells, offering new insights into its bioactivity and potential health risks.

Fluorinated Aminopiperidones as Non‐Glutarimide Thalidomide Analogs: Stereodivergent Synthesis and Validation

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
Fluorinated aminopiperidones, designed as non‐glutarimide thalidomide analogs, were synthesized with full regio‐ and stereocontrol. The C*–CF3 used as carbonyl surrogate improved solubility and membrane interactions while abolishing cereblon binding.
