5-Benzyl-5H-pyrido[3,2-b]indole
The title compound, C(18)H(14)N(2), was prepared by twofold Pd-catalyzed aryl-amination of a cyclic pyrido-benzo-iodo-lium salt. In the crystal, two mol-ecules of 9-benzyl-δ-carboline form centrosymmetrical dimers with distances of 3.651 (2) Å between the centroids of the pyridine rings and 3.961 (2) Å between the centroids of the pyrrole and pyridine rings. The phenyl rings point to the other ...
متن کامل5-Benzyl-2-phenyl-6,8-dihydro-5H-1,2,4-triazolo[3,4-c][1,4]oxazin-2-ium hexafluoridophosphate
The title compound, C(18)H(18)N(3)O(+)·PF(6) (-), is a chiral bicyclic 1,2,4-triazolium salt which contains four rings, viz. a triazolium, a morpholine and two phenyl rings. Analysis of bond lengths shows that the N-CH-N group in the triazolium ring conforms to a typical three-center/four-electron bond (also known as the Pimentel-Rundle three-center model). The structure is completed by a disor...
متن کامل2-Methyl-1,10b-dihydro-5H-pyrazolo[1,5-c][1,3]benzoxazin-5-one
In the title compound, C(11)H(10)N(2)O(2), a potential inhibitor of the cyclo-oxygenase-2 isoenzyme, the pyrazoline ring exists in a flat-envelope conformation while the puckering of the central oxazine ring is more severe. As a result, the mol-ecule as a whole is non-planar. The formal sp(3) pyrazoline N atom is sp(2) hybridized, with the lone-pair electrons delocalized through conjugation wit...
متن کامل2-(Furan-2-yl)-5-(2-nitrobenzyl)-2,3-dihydro-1,5-benzothiazepin-4(5H)-one
The title compound, C(20)H(16)N(2)O(4)S, was prepared by introduction of a 2-nitro-benzyl group to 2-(furan-2-yl)-2,3-dihydro-1,5-benzothia-zepin-4(5H)-one via an alkaline-catalysed reaction. The thia-zepine ring adopts a twist-boat conformation. The furan ring is oriented at dihedral angles of 56.75 (14) and 10.82 (14)° with respect to the two benzene rings, while the two benzene rings make a ...
متن کامل(5R*,11R*)-5-Methyl-1,2-dihydro-5,11-methano-5H,11H-1,3-thiazolo[2,3-d][1,3,5]benzoxadiazocine
The title compound, C(13)H(14)N(2)OS, crystallizes as a racemate in a non-chiral space group. It represents a conformationally restricted analogue of so-called Biginelli compounds known to exhibit multiple pharmacological activities and was selected for a single-crystal X-ray analysis in order to probe the chemical and spatial requirements of some kinds of activity. It was found that the state ...
