Ethyl ent-15?-[(2-nitro-benz-yloxy)meth-yl]-16-oxobeyeran-20-oate.

ABSTRACT: In the title compound, C(30)H(41)NO(6), the three six-membered rings adopt chair conformations and the stereochemistry of the A/B and B/C ring junctions are trans. The five-membered ring D adopts an envelope conformation, with the methyl-ene C atom as the flap. The title compound was synthesized via esterification, Tollens reaction, 1,5-hydride shift from the natural tetracyclic diterpenoid isosteviol.

1-[(3-Benz-yloxy-2-nitro-phen-oxy)meth-yl]benzene.

Project description:The asymmetric unit of the title compound, C(20)H(17)NO(4), consists of two crystallographically independent mol-ecules. In one of the mol-ecules, the central benzene ring forms dihedral angles of 2.26?(6) and 58.68?(6)° with the terminal benzene rings and the dihedral angle between the terminal benzene rings is 56.45?(6)°. The corresponding values for the other mol-ecule are 35.17?(6), 70.97?(6) and 69.62?(6)°, respectively. In the crystal, an inversion dimer linked by a pair of C-H?O hydrogen bonds occurs for one of the unique mol-ecules. C-H?? and ?-? [centroid-centroid distances = 3.7113?(8) and 3.7216?(7)?Å] inter-actions link the components into a three-dimensional network.

15?,20?-Dihydr-oxy-6?-meth-oxy-6,7-seco-6,20-ep-oxy-1,7-olide-ent-kaur-16-ene.

Project description:The title compound, C(21)H(30)O(6), a natural ent-kaurane diterpenoid, was obtained from the medicinal plant Isodon serra. The five rings in the mol-ecule exhibit the expected cis and trans junctions. The three six-membered rings adopt chair, twist-boat and boat conformations, while two five-membered rings adopt envelope conformations. There are two mol-ecules in the asymmetric unit, related by a non-crystallographic twofold screw axis; the main difference is in the different degrees of distortion of ring B. In the crystal, the mol-ecules are linked by inter-molecular O-H?O hydrogen bonds, forming chains along the b axis.
