Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
This shows indene derivatives. Under the reaction conditions of a Friedel–Crafts acylation, alkyl benzenes underwent an unprecedented cyclopentannulation furnishing indene derivatives. Alkylbenzene derivatives react with two equivalents of pivaloyl chloride (PivCl) in the presence of aluminum trichloride under formation of indene derivatives with up to

Dibenzosuberene‐Winged Polycyclic Aromatic Hydrocarbons

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
The twisted acene 8, which features two dibenzosuberene “wings”, was prepared by the addition of a crowded aryne to a similarly “winged” cyclopentadienone. Compound 8 is chiral, and it has a high barrier to thermal racemization (ΔG‡rac = 36 kcal/mol), but it undergoes fast photochemical racemization even in ambient light.

Bioconjugation Strategies for Revealing the Roles of Glycerophospholipids in Cells

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Glycerophospholipids are the main class of phospholipids, essential for membrane structure, compartmentalization, and cellular signaling. To study their roles, innovative probes and advanced bioconjugation strategies have been developed, including by de novo lipid synthesis and bioorthogonal conjugation chemistry.
