M?bius Aromatic Core-Modified Heterocyclic [20] Macrocycles (4.1.1) with a Protruding N-Methyl Pyrrole Ring

, p. 986 - 990 (2016)
Herein, we report the first synthesis of an unorthodox tripyrrane moiety from the regioselective β-benzoylation of pyrrole and the acid-catalyzed condensation of the desired precursors. A [3+1] Mac Donald type condensation strategy for this tripyrrane has led to the exclusive isolation of two hitherto-unknown aromatic [20] heterocyclic macrocycles (4.1.1).

High yield synthesis and spectroscopic isolation of two hitherto unknown highly stable single conformers of meso-aryl substituted dithia/diselena trans-doubly N-confused porphyrins with fully π-conjugated [18] annulene structures are reported. In-depth solution state spectroscopic measurements and DFT level theoretical calculations strongly show the distinct aromaticity with strong NIR absorption of these new macrocycles. This journal is
Core-modified porphyrins. Part 4: Steric effects on photophysical and biological properties in vitro
You, Youngjae,Gibson, Scott L.,Hilf, Russell,Ohulchanskyy, Tymish Y.,Detty, Michael R.

21,23-Dithiaporphyrins (2-10) were designed and prepared as analogues of 5,20-diphenyl-10,15-bis(4-carboxylatomethoxy)phenyl-21,23-dithiaporphyrin (1) to examine the impact of steric bulk at the 5- and 20-meso positions as well as the impact of symmetry.
Water-soluble, core-modified porphyrins as novel, longer-wavelength-absorbing sensitizers for photodynamic therapy. II. Effects of core heteroatoms and meso-substituents on biological activity
Hilmey, David G.,Abe, Masako,Nelen, Marina I.,Stilts, Corey E.,Baker, Gary A.,Baker, Sheila N.,Bright, Frank V.,Davies, Sherry R.,Gollnick, Sandra O.,Oseroff, Allan R.,Gibson, Scott L.,Hilf, Russell,Detty, Michael R.

Water-soluble, core-modified porphyrins were prepared and evaluated as sensitizers for photodynamic therapy (PDT). The addition of an aromatic aldehyde to 2,5-dilithiothiophene or -selenophene gave diol 3 as a nearly equimolar mixture of meso and d,1 dias
