Ethyl (E)-3-[1′-ethyl-2-oxo-4′-(phenylsulfonyl)-2H-spiro[acenaphthylene-1,2′-pyrrolidine]-3′-yl]acrylate
In the title compound, C(28)H(27)NO(5)S, the five-membered pyrrolidine ring, which exhibits an envelope conformation (the C atom at the spiral junction being the flap atom), makes dihedral angles of 57.37 (10) and 86.84 (8)°, respectively, with the phenyl ring and the acenaphthyl-ene ring system. In the crystal, mol-ecules associate via two C-H⋯O hydrogen bonds, forming R(2) (2)(20) and R(2) (2...
متن کامل2-Oxo-2-(2-oxo-2H-chromen-3-yl)ethyl pyrrolidine-1-carbodithioate
There are two independent mol-ecules in the asymmetric unit of the title compound, C16H15NO3S2, in which the pyrrolidine rings adopt envelope conformations, with a methyl-ene C atom as the flap. The dihedral angles betweeen the near-planar 2H-chromene ring systems [maximum deviations = 0.0167 (20) and 0.0136 (19) Å] and the pyrrolidine rings (all atoms) are 83.83 (11) and 82.43 (11)°. In the cr...

In the title compound, C(26)H(22)N(2)O(3), the acenaphthen-1-one ring system is nearly planar and the pyrrolidine ring adopts a distorted envelope conformation. An inter-molecular C-H⋯O hydrogen bond stabilizes the crystal structure.
متن کاملEthyl 6-(4-methoxyphenyl)-2-oxo-4-phenylcyclohex-3-enecarboxylate
The asymmetric unit of the title compound, C(22)H(22)O(4), consists of two independent mol-ecules (A and B). The cyclo-hexene rings adopt slightly distorted sofa conformations in both mol-ecules. The dihedral angles between the benzene rings are 74.16 (13) and 71.85 (13)° in mol-ecules A and B, respectively. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into a ribbon-like struct...
متن کاملEthyl 2-(3-acetyl-6-methyl-2-oxo-2H-pyran-4-yloxy)acetate
The title compound, C(12)H(14)O(6), features a roughly planar mol-ecule (r.m.s. deviation for all non-H atoms = 0.287 Å). In the crystal, the mol-ecules are held together by C-H⋯O hydrogen bonds.
