Electric Literature of C10H9NO2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-Methoxy-1H-indole-2-carbaldehyde, is researched, Molecular C10H9NO2, CAS is 21778-81-4, about Synthesis of carbazole derivatives. III. Synthesis of new pyrrolidino[3,4-c]carbazoles by intramolecular Michael addition. Author is Mahboobi, Sioavosh; Kuhr, Sabine; Koller, Markus.
The authors have reported on the synthesis of carbazoles by inter- and intramol. Michael addition Ellipticine derivatives are related to these compounds, and especially those with 9-methoxy- and 9-hydroxy substituents exhibit appreciable antitumor and antileukemic activity. Therefore, the authors have prepared the tetrahydrocarbazoles I (R1 = OMe, R2 = H; R1 = H, R2 = OMe), starting from N-benzyl-2-formyl-5-methoxyindole and N-benzyl-2-formyl-7-methoxyindole, resp.
