PTC in the Polyenolate‐Mediated [10+2]‐Cycloaddition for the Synthesis of α,α‐Disubstituted Amino Acid Precursors

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 8, April 15, 2025.
Abstract The manuscript describes a formal [10+2] higher‐order cycloaddition between 2‐arylideneindan‐1‐ones and α‐alkylidene azlactones as higherene precursors and higherenofiles respectively. The reaction is realized under Brønsted‐base catalysis utilizing the phase transfer catalysis approach.

Panchromatic Absorption of Unsymmetrical Donor‐Acceptor Dyes Based on a Meta‐Conjugated 1,3,5‐Heteroaryltriazine Core

open access: yesChemistry – A European Journal, Volume 31, Issue 11, February 20, 2025.
Little explored are 1,3,5‐triazine cores that are substituted with three different heteroaromatic groups despite their distinct optical and electronic properties. 1,3,5‐Triazines substituted with strong donor and acceptor thiophenes give rise to long wavelength absorption tails due to intramolecular charge transfer absorptions of the meta‐conjugated ...
