N-[(2S)-4-Chloro-2-(l-menthyloxy)-5-oxo-2,5-dihydro-3-furyl]-l-alanine
The title compound, C(17)H(26)ClNO(5), was prepared via a tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)furan-2(5H)--one and l-alanine in the presence of potassium hydroxide. The five-membered furan-one ring is approximately planar while the six-membered menth-yloxy ring adopts a chair conformation. The crystal packing is stabilized by inter-molec...
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)°.
متن کامل5-Chloro-3-(4-fluorophenylsulfonyl)-2,7-dimethyl-1-benzofuran
In the title compound, C16H12ClFO3S, the dihedral angle between the plane of the benzo-furan ring system [r.m.s. deviation = 0.007 (1) Å] and that of the 4-fluoro-phenyl ring is 76.11 (5)°. In the crystal, mol-ecules are linked into [010] chains via two different inversion-generated pairs of C-H⋯O hydrogen bonds. The crystal structure also exhibits weak π-π inter-actions between the benzene and...
متن کامل3-(4-Bromophenylsulfinyl)-5-chloro-2,7-dimethyl-1-benzofuran
In the title compound, C16H12BrClO2S, the 4-bromo-phenyl ring makes a dihedral angle of 88.84 (5)° with the mean plane [r.m.s. deviation = 0.009 (1) Å] of the benzo-furan fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-S⋯π [3.386 (2) Å] inter-actions, forming a chain perpendicular to the bc plane.
متن کاملThree-dimensional quantitative structure activity relationship approach series of 3-Bromo-4-(1-H-3-Indolyl)-2, 5-Dihydro-1H-2, 5- Pyrroledione as antibacterial agents
The use of quantitative structure–activity relationships, since its advent, has becomeincreasingly helpful in understanding many aspects of biochemical interactions in drug research.This approach was utilized to explain the relationship of structure with biological activity ofantibacterial. For the development of new fungicides against, the quantitative structural–activityrelationship (QSAR) an...
