Isolation and synthesis of biologically active carbazole alkaloids

Two-dimensionally extended, polycyclic heteroaromatic molecules (heterocyclic nanographenes) are a highly versatile class of organic materials, applicable as functional chromophores and organic semiconductors. In this Review, we discuss the rich chemistry of large heteroaromatics, focusing on their synthesis, electronic properties, and applications in materials science. This Review summarizes the historical development and current state of the art in this rapidly expanding field of research, which has become one of the key exploration areas of modern heterocyclic chemistry.

Heterocyclic Nanographenes and Other Polycyclic Heteroaromatic Compounds: Synthetic Routes, Properties, and Applications

Les spectres de masse du benzisothiazole, de trois benzoselenzoles et de trois benzisoseleazoles not ete mesures et compares a ceux des benzothiazoles correspondants. La perte de CS mise en evidence chez ces derniers est confirmee dans le cas du benzisothiazole, mais un mecanisme different est propose.



La fragmentation des analogues selenies conduit a des ions du meme type que dans le cas des benzothiazoles et du benzisothiazole par perte de molecules du type CN—R, cependant, la perte de l'heteroatome ne s'accompagne pas de perte de carbone. En outre, il semble que la structure isoselenazole soit plus sensible a l'electronolyse que son isomere.



Les six heterocycles selenies etudies ont tous donne naissance a deux ions (130 et 132) provenant d'une recombinaison de divers fragments. Ce phenomene laisse a penser qu'il s'agit la d'un element caracteristique dans la fragmentation electronique de tels composes.



The mass spectra of benzisothiazole, three benzoselenazoles and three benzisoselenazoles have been determined and compared with those of the corresponding benzothiazoles. The elimination of CS known to occur from these latter substances is confirmed in the case of benzisothiazole, but a different mechanism is proposed.



The fragmentation of the selenium analogues led to ions of the same type as the benzothiazoles and benzisothiazole, through extrusion of molecules of the type CN—R, but loss of the heteroatom was not accompanied by loss of carbon. Furthermore, the isoselenazole structure seems to be more sensitive to electronolysis than its isomer.



All six selenium heterocyclics investigated gave rise to two ions (130 and 132) resulting from a recombination of various fragments, suggesting that this is a characteristic feature of the electron-impact fragmentation of compounds of this type.
