1-(5-Hydroxy-7-methoxy-2,2-dimethyl-2H-chromen-6-yl)ethan-1-one
The title chromene, C(14)H(16)O(4), was isolated from the stems of Polyalthia plagioneura Diels. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions, generating [010] chains.

In the title mol-ecule, C(16)H(19)BrO(3), all non-H atoms apart from the Br atom are approximately coplanar, with a maximum deviation of 0.242 (4) Å. The C-C-C-Br torsion angle is 66.5 (4)°.
متن کامل7-Hydroxy-6-methoxy-2H-chromen-2-one
The title compound, C(10)H(8)O(4), is one of the coumarins existing in Morinda citrifolia L (Noni). The chromenone ring system is approximately planar with a maximum deviation of 0.0208 (14) Å. The meth-oxy group does not deviate from this plane [C-O-C-C torsion angle = -1.5 (3)°], indicating that the whole mol-ecule is almost planar. In the crystal packing, inter-molecular O-H⋯O hydrogen bonds...
متن کامل3-(2-Bromoacetyl)-6-fluoro-2H-chromen-2-one
The non-H atoms of the title compound, C(11)H(6)BrFO(3), are essentially coplanar (r.m.s. deviation for all non-H atoms = 0.074 Å). In the crystal, the molecules are linked by C-H⋯O and C-H⋯Br inter-actions.
متن کامل3,6,8-Tribromo-7-ethylamino-4-methyl-2H-chromen-2-one
In the title mol-ecule, C(12)H(10)Br(3)NO(2), the 2H-chromen ring is essentially planar (r.m.s. deviation = 0.022 Å) with the ethyl-amino group oriented at 13.9 (5)° with respect to the ring. The mol-ecular structure is stabilized by intra-molecular N-H⋯Br and C-H⋯Br interactions.
