Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 67929-86-6, is researched, SMILESS is O=C(C(N1)=CC2=C1C=CC(OC)=C2)OC, Molecular C11H11NO3Journal, Article, European Journal of Medicinal Chemistry called Concise synthesis of carbazole-1,4-quinones and evaluation of their antiproliferative activity against HCT-116 and HL-60 cells, Author is Nishiyama, Takashi; Hatae, Noriyuki; Yoshimura, Teruki; Takaki, Sawa; Abe, Takumi; Ishikura, Minoru; Hibino, Satoshi; Choshi, Tominari, the main research direction is carbazolequinone preparation antiproliferative human; indole allyl alc tandem ring closing metathesis dehydrogenation; Antiproliferative activity; Carbazole-1,4-quinone; Koeniginequinone A; Koeniginequinone B.Quality Control of Methyl 5-methoxyindole-2-carboxylate.
A convenient synthesis of carbazole-1,4-quinone alkaloid koeniginequinones A and B using a tandem ring-closing metathesis with the dehydrogenation reaction sequence under an O2 atmosphere as an important step is reported. Using this method, carbazole-1,4-quinones substituted at the 5-, 6-, 7-, and/or 8-positions I (R1 = R2 = H, CH3; R3 = H, 6-OCH3, 5,6-(OCH3)2, 7-CH3, 6-NO2, etc.; R4 = H, MOM) have been synthesized. Moreover, 24 compounds, including koeniginequinones A and B, have been evaluated for their antiproliferative activity against HCT-116 and HL-60 cells, and the 6-nitro analog exhibited the most potent activity against both tumor cell types.
