Abstract: The reactions of alkyl 3-nitroacrylates and ethyl 2-(1-methyl-1H-indol-3-yl)-3-nitroacrylate with о-aminothiophenol, о-aminophenol, о-phenylenediamine, and their substituted analogs were used for the preparation of 2-(nitromethyl)-2H-1,4-benzothiazin-3(4H)-one, 2-(1-methyl-1H-indol-3-yl)-2-(nitromethyl)-2H-1,4-benzothiazin-3(4H)-one, 3-methyl-2H-1,4-benzoxazin-2-ones, and 3-(1-methyl-1H-indol-3-yl)quinoxalin-2(1H)-ones that were structurally characterized. read more here.

Abstract: Four 2,2'-bisindolylmethanes (BIMs), a useful class of polyindolyl species joined to a central carbon, were synthesized using salicylaldehyde derivatives and simple acid catalysis; these are 2-[bis(3-methyl-1H-indol-2-yl)methyl]-6-methylphenol, (IIa), 2-[bis(3-methyl-1H-indol-2-yl)methyl]-4,6-dichlorophenol, (IIb), 2-[bis(3-methyl-1H-indol-2-yl)methyl]-4-nitrophenol, (IIc), and 2-[bis(3-methyl-1H-indol-2-yl)methyl]-4,6-di-tert-butylphenol, (IId). BIMs… read more here.
