11-(3-Chloro-2-hydroxy-prop-oxy)-2,3,9-trimethoxy-chromeno[3,4-b]chromen-12(6H)-one.

ABSTRACT: In the title compound, C(22)H(21)ClO(8), the rotenoid core is nearly planar (r.m.s. deviation 0.114?Å), with the largest deviations from the least-squares plane being 0.286?(3) and 0.274?(2)?Å. An inter-molecular O-H?O hydrogen bond links two mol-ecules into a centrosymmetric dimer having an R(2) (2)(18) ring motif.

Novel 6a,12b-Dihydro-6H,7H-chromeno[3,4-c] chromen-6-ones: Synthesis, Structure and Antifungal Activity.

Project description:A new series of coumarin derivatives, 7-hydroxy-7-(trifluoromethyl)-6a,12b-dihydro-6H,7H-chromeno[3,4-c]chromen-6-ones 3a-p, were synthesized via Michael addition, transesterification and nucleophilic addition from the reaction of 3-trifluoroacetyl coumarins and phenols in the presence of an organic base. The products were characterized by infrared spectroscopy (IR), hydrogen nuclear magnetic resonance spectroscopy (1H-NMR), carbon nuclear magnetic resonance spectroscopy (13C-NMR) and high-resolution mass spectrometer (HRMS). Single crystal X-ray analysis of compounds 3a and 3n clearly confirmed their assigned chemical structures and their twisted conformations. Compound 3a crystallized in the orthorhombic system, Pbca, in which a = 8.6244(2) Å, b = 17.4245(4) Å, c = 22.5188(6) Å, α = 90°, β = 90°, γ = 90°, v = 3384.02(14) Å3, and z = 8. In addition, the mycelial growth rate method was used to examine the in vitro antifungal activities of the title compounds 3a-p against Fusarium graminearum and Fusarium monitiforme at 500 µg/mL. The results showed that compound 3l exhibited significant anti-Fusarium monitiforme activity with inhibitory index of 84.6%.

Project description:The title co-crystal, 0.95C(20)H(20)O(3)·0.05C(20)H(19)ClO(3), arises as the chloride carried over during the synthesis shares a position with an aromatic H atom; the partial occupancies are 0.947?(2) and 0.053?(2) for H and Cl, respectively. The mol-ecular structure is stabilized by intra-molecular C-H?O contacts, forming pseudo five- and six-membered rings with S(5) and S(6) graph-set motifs, respectively. The crystal structure features ?-? stacking inter-actions between the centroids of the central fused ring systems [centroid-centroid distance = 3.501?(2)?Å].

Crystal structure of 4-methyl-7-prop-oxy-2H-chromen-2-one.

Project description:The asymmetric unit of the title compound, C13H14O3, contains two independent mol-ecules, A and B, that are inter-connected through an offset π-π inter-action [inter-centroid separation = 3.6087 (4) Å]. The fused benzene and pyran-2-one rings in each mol-ecule are essentially coplanar, having dihedral angles of 1.22 (12) and 1.57 (12)° for mol-ecules A and B, respectively. Similarly, the coumarin ring system and the 7-prop-oxy substituent are close to being coplanar [C-C-O-C torsion angles = 2.9 (2) and 1.4 (2)° for mol-ecules A and B, respectively]. In the crystal, the mol-ecules are connected by C-H⋯O hydrogen bonds, forming supra-molecular tapes along [100] that are linked into a three-dimensional network by C-H⋯π inter-actions, as well as by the aforementioned π-π inter-actions.
