Prodigiosin is the parent compound of the tripyrrolic natural products known as the prodigiosenes. Some of these natural products and their synthetic analogs show anti-cancer, immunosuppressive and antimicrobial actions, ...

Several analogues of the natural compound prodigiosin with modified A- and C-rings were synthesised as were some of their tin, cobalt, boron and zinc complexes. The antimalarial activity of these prodigiosenes was evaluated ...

The activation of F-BODIPYs with boron trihalides, followed by treatment with a nuclephile, effects facile substitution at boron; using water as the nucleophile promotes deprotective removal of the–BF2 moiety and thereby ...

Benzyl esters are cleaved upon reaction with SnCl4, resulting in isolation of the corresponding carboxylic acid. Importantly, benzyl ethers, amines and amides do not undergo debenzylation under these conditions, nor do a ...

The reaction of 2-formyl pyrroles in acidic methanol gives the corresponding symmetric, meso-H 4,6-dipyrrin hydrobromides. This convenient strategy involves initial deformylation under the acidic conditions, followed by ...
