Decarboxylative Arylation of Substituted Pyrroles N-protected with 2-(Trimethylsilyl) ethoxymethyl (SEM)
(Canadian Journal of Chemistry, 2018)
Palladium-catalyzed decarboxylative arylation is reported using pyrroles N-protected with the 2-(trimethylsilyl) ethoxymethyl (SEM) group and featuring 2-, 3- and 4-substituents about the pyrrolic framework. In contrast ...

Synthesis and Characterization of Pyrrolyldipyrrin F-BODIPYs
(Photochemical and Photobiological Sciences, 2018)
A series of synthetic analogs of the tripyrrolic natural product prodigiosin were complexed with boron trifluoride to generate the corresponding F-BODIPYs. The maximum wavelengths of absorption and emission of the ...
Photo-induced Anticancer Activity and Singlet Oxygen Production of Prodigiosenes
(2018)
The photo-induced cytotoxicity of prodigiosenes is reported. One prodigiosene represents a synthetic analogue of the natural product prodigiosin, and two are conjugated to molecules that target the estrogen receptor (ER). ...
Regioselective Substituent Effects upon the Synthesis of Dipyrrins from 2-Formyl Pyrroles
(Canadian Journal of Chemistry, 2018)
The synthesis of symmetric α-free meso-H-dipyrrin hydrobromides from 5-H-2-formyl pyrroles was investigated. The self-condensation produces regioisomeric dipyrrins through the adoption of two mechanistic pathways. The key ...
Synthesis and Reactivity of Aza-Dipyrrin Alkali Metal Salts
(Chemical Communications, 2018)
We report the lithium, sodium and potassium salts of aza-dipyrrins and detail their use as anionic aza-dipyrrinato ligand sources in complexation. Of the three types of alkali salts studied, those of lithium are found to ...
