Journal ArticleDOI
Supramolecular hydrogen-bonded hexamers in two 5-aryl-3-methyl-1-phenyl-1,6,7,8-tetrahydropyrazolo[3,4-b][1,4]diazepines.
TL;DR: In both title compounds, i.e. 3-methyl-1-5-diphenyl-1,6,7,8-tetrahydropyrazolo[3,4-b][1,4]diazepine, C(19)H(17)ClN(4), (II), an N-H...N hydrogen bond links six molecules to form an R(6)(6)(30) ring.
Journal ArticleDOI
A concise and versatile route to tetrahydro-1-benzazepines carrying [a]-fused heterocyclic units: synthetic sequence and spectroscopic characterization, and the molecular and supramolecular structures of one intermediate and two products.
TL;DR: A concise, efficient and versatile route from simple starting materials to tricyclic tetrahydro-1-benzazepines carrying [a]-fused heterocyclic units is reported.
Journal ArticleDOI
3,5-Dimethyl-1,7-diphenyl-4-(2-pyridyl)-1H,7H-pyrazolo[3,4-b:4′,3′-e]pyridine
TL;DR: In the title compound, C26H20N6, the supramolecular structure is determined by a weak C-H⋯N hydrogen bond which links the molcules into chains running parallel to [110] as mentioned in this paper.
Journal ArticleDOI
2,5-Dimethyl-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline and 2-tert-butyl-5-methyl-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline.
TL;DR: In both 2, 5-dimethyl-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline, C(16)H(15)N(3), (I), and 2-tert-butyl-5-methyl-6-7- dihydrosine-like-likelihood-reducing-reduction-reductions-of-one-another, the non-aromatic
