3-(2,3,5,6,7,8-Hexahydro-1H-cyclopenta[b]quinolin-9-yl)-1,5-bis(4-methoxyphenyl)biuret
Ipidacrine (2,3,5,6,7,8-hexa-hydro-1H-cyclo-penta-[b]quinolin-9-amine) was reacted with 4-methoxy-phenyl isocyanate to give the title compound, C(28)H(30)N(4)O(4). An intra-molecular N-H⋯O hydrogen bond results in an essentially planar [r.m.s. deviation from the mean plane is 0.126 (1) Å] conformation for the biuret unit. The central ring of the quinoline unit is twisted by 78.2 (1)° with respe...
متن کامل3-Ethyl-9-phenyl-2-tosyl-2,3,3a,4,9,9a-hexahydro-1H-pyrrolo[3,4-b]quinoline
In the mol-ecule of the title compound, C(26)H(28)N(2)O(2)S, the pyrrolidine ring adopts an envelope conformation and the tetra-hydro-pyridine ring is in a half-chair conformation; these two rings are trans-fused. The dihedral angle between the pyridine- and sulfonyl-bound benzene rings is 36.15 (5)°. In the crystalline state, the mol-ecules are linked into a two-dimensional network parallel to...
متن کاملAn efficient copper-catalyzed synthesis of hexahydro-1H- phenothiazines.
Hexahydro-1H-phenothiazine moieties can be synthesized by domino aziridine ring opening with o-halothiophenols followed by copper-catalyzed Goldberg coupling-cyclization with good to excellent yields. Less reactive o-chlorothiophenols are also successfully utilized for the domino reaction to synthesize phenothiazine derivatives. This methodology is successfully applied in the synthesis of pheno...
متن کامل4-(1H-Tetrazol-5-yl)benzene-1,3-diol
In the title compound, C7H6N4O2, rings are almost coplanar, the dihedral angle between them being 8.45 (13)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, the mol-ecules are linked by O-H⋯N and N-H⋯O hydrogen bonds into a three-dimensional network.
متن کاملent-5α,3,15-Dioxodolabr-4(18)-ene-16,18-diol
The title compound, C(20)H(30)O(4), is a dolabrane diterpenoid isolated from Ceriops tagal, in which one of the three fused cyclo-hexane rings adopts a half-chair conformation and the other two are in the standard chair conformations. The hy-droxy-methyl-idene substituent is attached to the half-chair cyclo-hexane. An intra-molecular O-H⋯O hydrogen bond generate an S(6) ring motif. In the cryst...
