rac-3-(4-Hydroxybenzyl)chroman-4-one
In the racemic title compound, C16H14O3, the ring of the 4-hy-droxy-benzyl substituent group forms a dihedral angle of 80.12 (12)° with the benzene ring of the chromanone system. Two C atoms of the pyran-one ring and the H atoms on the benzyl α-C atom are disordered over two sites, with site-occupation factors of 0.818 (8) and 0.182 (8). The crystal structure is stabilized by O-H⋯O hydrogen bon...

In the title compound, C(18)H(17)Cl(2)NOS, the thio-pyran-one ring adopts a chair conformation, with the substituent in the axial position. The dihedral angle between the two benzene rings is 89.43 (1)°. In the crystal, mol-ecules form inversion dimers through inter-molecular N-H⋯O hydrogen bonds [graph set R(2) (2)(8)].

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].

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 کاملrac-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...
