(6,6-Dimethyl-1-phenyl-6,7-dihydro-5H-pyrrolizin-2-yl)(thiophen-2-yl)methanone
In the title compound, C20H19NOS, the pyrrolizine ring is essentially planar (r.m.s. deviation = 0.001 Å) while the fused dihydro-pyrrolizine ring adopts an envelope comformation with the C atom bearing the methyl substituents as the flap. The dihedral angles between the pyrrolizine and the phenyl and thio-phene rings are 34.54 (7) and 44.93 (7)°, respectively. In the crystal, weak C-H⋯O hydrog...
متن کامل(E)-2-(2-Furylmethylidene)-2,3-dihydro-1H-pyrrolizin-1-one
The title compound, C(12)H(9)NO(2), was prepared by an Aldol reaction of furfuraldehyde with 2,3-dihydro-1H-pyrrolizin-1-one. The mol-ecule is almost planar, with an r.m.s. deviation of 0.045 Å, excluding the methyl-ene H atoms. In the crystal structure, mol-ecules are linked via weak inter-molecular C-H⋯O hydrogen bonding and aromatic π-π stacking [centroid-centroid distance = 3.6151 (9) Å].

In the title compound, C(20)H(22)N(2)O(3)S, the oxazoline ring is planar (r.m.s. deviation = 0.045 Å) and forms dihedral angles of 47.24 (8) and 10.11 (8)° with the S- and C-bound phenyl rings, respectively. The nitro group lies to the same side of the mol-ecule as the oxazoline ring but is orientated so as not to inter-act with the ring. Linear supra-molecular chains along [010] are formed via...
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 کامل1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-aminium chloride–thiourea (1/1)
In the title compound, C(11)H(14)N(3)O(+)·Cl(-)·CH(4)N(2)S, the components are connected into a two-dimensional polymeric structure parallel to (001) via N-H⋯Cl, N-H⋯O, N-H⋯S and C-H⋯S hydrogen bonds. The dihedral angle between the phenyl and 2,3-dihydro-1H-pyrazole rings is 44.96 (7)°.
