In the title mol-ecule, C(15)H(13)NOS, the two benzene rings of the tricyclic fused-ring system are inclined at 21.1 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into chains along [001]. The crystal packing also exhibits π-π inter-actions with a distance of 3.801 (5) Å between the centroids of the benzene rings of neighbouring mol-ecules.

The title compound, C(21)H(24)N(4)S(3), is a tripodal Schiff base that was obtained from the reaction of tris-(2-amino-eth-yl)amine (tren) and thio-phene-3-carbaldehyde. The compound forms a cavity with approximate C3 symmetry. One of the thio-phene units is disordered in a 0.764 (2):0.236 (2) ratio. In the crystal, the three thio-phene ligands are involved in intra-molecular C-H⋯π inter-action...

(E)-3-(1-Benzofuran-2-yl)propenoic acid (I) was prepared from 1-benzofuran-2-carbaldehyde under the Doebner’s conditions. The obtained converted to corresponding azide II, which cyclized by heating in diphenyl ether [1]benzofuro[3,2-c]pyridin-1(2H)-one (III). This compound aromatized with phosphorus oxychloride chloroderivative IV reduced zinc and acetic title V. [1]Benzofuro[3,2-c]pyridin-2-ox...

The synthesis and structural diversification of N-heterocycles systems have attracted much attention because their potential applications. Three 6-aryl-3-methyl-1-phenyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde 4 derivatives, in reaction with acetophenones 5, via conventional Claisen–Schmidt condensation reactions, generated the respective enones. enones were used as electron-deficient olefins...
