9a-Hydroxy-3,8a-dimethyl-5-methylene-4,4a,5,6,9,9a-hexahydronaphtho[2,3-b]furan-2(8aH)-one
The title compound, C(15)H(18)O(3), was isolated from Lacta-rius piperatus (Fr.) S. F. Gary collected from the Kunming area in Yunnan province, China. The central cyclo-hexyl ring adopts a chair conformation, while the furan-one ring is close to planar (r.m.s. deviation = 0.0174 Å). The remaining methyl-ene cyclo-hexene ring has a flattened chair conformation. In the crystal, mol-ecules are lin...
متن کامل2,4-Bis(furan-2-yl)-1,5-dimethyl-3-azabicyclo[3.3.1]nonan-9-one
In the title compound, C18H21NO3, the bicyclic ring system adopts a twin-chair conformation. The two methyl groups attached to the bicycle are in an equatorial orientation for both rings. One of the furan rings is disordered over two orientations with an occupancy ratio of 0.686 (6):0.314 (6). In the crystal, very long N-H⋯O hydrogen bonds connect the mol-ecules into a chain perpendicular to th...
متن کاملCrystal structure of (E)-1-(3-chlorophenyl)-3-(furan-2-yl)prop-2-en-1-one
The title compound, C13H9ClO2, exhibits a non-planar geometry; the furan ring being inclined to the benzene ring by 50.52 (16)°. In the crystal, mol-ecules stack along the a axis; however, there are no significant inter-molecular inter-actions present.
متن کاملCrystal structure of the chalcone (E)-3-(furan-2-yl)-1-phenylprop-2-en-1-one
The title chalcone derivative, C13H10O2, adopts an E conformation about the C=C double bond. The mol-ecule is composed of a furanyl and a phenyl ring, bridged by an α,β-unsaturated carbonyl system, which are inclined to one another by 24.07 (7)°. In the crystal, mol-ecules are connected by weak C-H⋯O hydrogen bonds involving the carbonyl O atom acting as a trifurcated acceptor and C-H⋯π inter-a...
متن کامل7-[2-(3-Furyl)ethyl]-7,8-dimethyl-3,5,6,6a,7,8,9,10-octahydro-1H-naphtho[1,8a-c]furan-3-one
In the title mol-ecule, C(20)H(26)O(3), a clerodane diterpenoid isolated from Dodonaea viscosa-, the trans-fused six-membered rings of the deca-line system display chair conformations. The five-membered lactone ring adopts an envelope conformation and the five-membered furan ring is essentially planar with a maximum deviation of 0.0052 (12) Å.
