We disclose an unprecedented single-step metal-free green oxidation of 2,7-di-tert-butylpyrene selectively into either the corresponding 4,5-dione or 4,5,9,10-tetraone, two key building blocks used for organic optoelectronic applications using hypervalent
Synthesis of C-2 arylated tryptophan amino acids and related compounds through palladium-catalyzed C-H Activation
Preciado, Sara,Mendive-Tapia, Lorena,Albericio, Fernando,Lavilla, Rodolfo
, p. 8129 - 8135 (2013/09/12)
Tryptophan (Trp) and tryptophan derivatives are C2-arylated. A C-H activation process allows the preparation of both protected and unprotected arylated-Trp amino acids, directly from the amino acid precursor and aryl iodides. The obtained compounds are suitable for standard solid-phase peptide synthesis.
Pyrene-fused porphyrins: Annulation reactions of meso-pyrenylporphyrins

We prepared novel pyrene-fused porphyrins via the oxidative intramolecular ring closure reactions of meso-pyrenylporphyrin. The excitation energies and the oxidation potentials of the isolated dark-colored pyrene-fused porphyrins were significantly low compared with those of the corresponding precursors.
