The title compound, C(20)H(20)N(6), was isolated from dimethyl sulfoxide solution using 2-(1H-imidazol-2-yl)pyridine and 1,4-dichloro-butane in the presence of NaOH.

The reactions of 2-perfluoroacyl-1H-benzo[f]chromenes and 6,7-dimethyl-3-trifluoroacetyl-4H-chromene with primary aliphatic amines ammonia afforded a series enamino ketones containing (2-hydroxynaphthalen-1-yl)methyl or 2-hydroxybenzyl substituent in the ?-position respect to carbonyl group. These involved opening pyran ring, which followed aza-Michael addition as initial step. obtained were fo...

The title compound, bis-[2,2'-dimethyl-3,3'-(butane-1,4-di-yl)diimidazol-1-ium] β-octa-molybdate(VI), (C(12)H(20)N(4))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4) and 1,4-bis-(2-methyl-1H-imidazol-1-yl)butane (hereafter L). The structure of the title compound consists of the β-octa-molybdate anions having a center of symmetry, and proto...

Black nightshade (Solanum nigrum L.) has been traditionally used as indigenous Chinese medicine. Phytochemical investigations of the immature fruits S. have carried out and nine phenylpropanoids (1-9) were obtained. Their structures elucidated on basis spectroscopic chemical methods, including MS, 1H 13C-NMR. They identified (7S, 8R)-4-[3-hydroxymethyl-5-(3- hydroxypropyl)-2,3-dihydrobenzofuran...
