rac-Methyl 4-azido-3-hydroxy-3-(2-nitrophenyl)butanoate
In the title compound, C(11)H(12)N(4)O(5), the mean plane through the nitro substituent on the benzene ring is inclined to the benzene mean plane by 85.8 (2)°, which avoids steric inter-actions with the ortho substituents. The hydr-oxy group is involved in bifurcated hydrogen bonds. The first is an intra-molecular O-H⋯O hydrogen bond, involving the ester carbonyl O atom, which gives rise to the...
متن کاملrac-3-[(Anilino)(naphthalen-2-yl)methyl]thian-4-one
In the title compound, C(22)H(21)NOS, the thio-pyran-one ring adopts a chair-like conformation with the substituent in the axial position. The relative configuration of the racemic compound is 3R,7S according to the numbering scheme used in this publication. In the crystal packing, centrosymmetric dimers are built up via N-H⋯O hydrogen bonds, with graph set R(2) (2)(8).
متن کاملMethyl 4-hydroxy-3-(3'-methyl-2'-butenyl)benzoate, major insecticidal principle from Piper guanacastensis.
The CHCl3-soluble extract of Piper guanacastensis (Piperaceae) was found to have noteworthy insecticidal activity to Aedes atropalpus mosquito larvae (LC50 80.5 micrograms/mL). Bioassay-guided fractionation afforded methyl 4-hydroxy-3-(3'-methyl-2'-butenyl)benzoate (1) as the major bioactive constituent (LC50 20.5 micrograms/mL). The separation of compound 1 from its transesterification artifac...

In the racemic title compound, C21H18O4, the chromone ring is essentially planar [maximum deviation from the least-squares plane = 0.026 (3) Å], with a dihedral angle of 78.18 (12)° between the benzene rings of the chromanone and chromenone moieties. In the crystal, there are weak π-π stacking inter-actions [minimum ring centroid separation = 3.9286 (17) Å].
متن کاملrac-2-[2-(4-Fluorophenyl)-2-oxo-1-phenylethyl]-4-methyl-3-oxo-N-phenylpentanamide
The title compound, C(26)H(24)FNO(3), is a critical inter-mediate of a selective and competitive inhibitor of the enzyme 3-hy-droxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase. Inter-molecular N-H⋯O hydrogen bonding generates a chain along [give direction] that is the dominant inter-action in the crystal packing. Inter-molecular C-H⋯O inter-actions are also observed.
