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

ABSTRACT: The title compound, C(31)H(44)O(5), was synthesized from isostev-iol (systematic name: ent-16-ketobeyeran-19-oic acid). In the mol-ecule, 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.

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.
