چکیده
The complete mol-ecule of the title compound, C(16)H(14)O(3), is generated by crystallographic mirror symmetry, with two C atoms and one O atom lying on the mirror plane. The mol-ecule adopts an E configuration about the C=C bond and the dihedral angle between the furan rings is 16.1 (2)°.

Iridoid biosynthesis in staphylinid rove beetles (Coleoptera: Staphylinidae, Philonthinae).
The biosynthesis of chrysomelidial and plagiodial was studied in the rove beetle subtribe Philonthina (Staphylinidae). Glandular homogenates were found to convert synthetic (2E,6E)-[trideuteromethyl-5,5-(2)H(5)]octa-2,6-diene-1,8-diol (10) into nor-chrysomelidial (14) and nor-plagiodial (13). The overall transformation requires; i) oxidation of the substrate at C(1) and C(8), ii) cyclization of...

The title compound, C(20)H(14)Cl(4)O, was prepared by the reaction of 2,6-dichloro-benzaldehyde and cyclo-hexa-none. In the mol-ecule, the central cyclo-hexa-none ring adopts an envelope conformation, while the terminal benzene rings make a dihedral angle of 57.87 (9)°.
متن کاملIsolation, Structure, and Absolute Configuration of a New Natural Insect Juvenile Hormone from Manduca sexta.
Two juvenile hormones are isolated from organ cultures of corpora allata of the tobacco hornworm moth, Manduca sexta Johannson, and are purified by high-resolution liquid chromatography. These are identified as methyl (2E, 6E)-(10R)-10,11-epoxy-3,7,11-trimethyl-2,6-dodecadienoate, a new natural hormone, and methyl (2E,6E) - (10R,11S) - 10,11 - epoxy - 3,7,11 - trimethyl-2,6-tridecadienoate.
