Oxidative Ring-Opening of 1H-Pyrazol-5-amines and Its Application in Constructing Pyrazolo–Pyrrolo–Pyrazine Scaffolds by Domino Cyclization

Herein, an oxidative ring-opening of 1H-pyrazol-5-amines to form 3-diazenylacrylonitrile derivatives under mild and transition-metal-free conditions is described. In addition, the nucleophilic addition of deprotonated 1H-pyrrole-2-carbaldehydes to the vinyl moiety of the yielded 3-diazenylacrylonitriles could trigger domino cyclization to afford the 3H-pyrazolo[3,4-e]pyrrolo[1,2-a]pyrazine derivatives. Computational studies suggest that the oxidation of 1H-pyrazol-5-amines in the presence of PhIO is through the formation of a hydroxylamine intermediate followed by elimination of H2O to result in the ring-opening product. The detailed domino cyclization pathway leading to the pyrazolo–pyrrolo–pyrazine scaffolds is revealed.

Selective bromination of pyrrole derivatives, carbazole and aromatic amines with DMSO/HBr under mild conditions

Bromination of pyrrole derivatives, carbazole and aromatic amines using the DMSO/HBr system affords high yields of the corresponding bromo compounds. Temperature control used in the bromination of anilines helped to promote selective formation of mono- or di-brominated products. Simple operation, low toxicity and high selectivity make this a promising new procedure for the bromination of aromatic compounds.

2- and 3-monohalogenated BODIPY dyes and their functionalized analogues: Synthesis and spectroscopy

Starting from appropriately halogenated acylpyrroles, a wide range of reactive 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) derivatives can be obtained. The fluorescent dyes display excellent reactivity in nucleophilic aromatic substitution, transi
