Fluorophores for Excited-State Intramolecular Proton Transfer by an Yttrium Triflate-Catalyzed Reaction of Isocyanides with Thiocarboxylic Acids

Fluorophores for Excited-State Intramolecular Proton Transfer by an Yttrium Triflate-Catalyzed Reaction of Isocyanides with Thiocarboxylic Acids
Shuo Tong, Qian Wang, Qing He, Jieping Zhu, Shun Zhao, Mei-Xiang Wang
The one-pot synthesis of 5-amino-4-carboxamidothiazole molecules by the yttrium triflate-catalyzed reaction of thiocarboxylic acids with isocyanides is reported by J. Zhu et al. in their Communication (DOI: 10.1002/anie.201702488). The resulting heterocycles are novel prototypical structures for the double excited-state intramolecular proton transfer (ESIPT) process and could serve as template for designing ESICT-to-ESIPT-coupled molecules (CT=charge transfer).
