Diterpenoids of the oleoresin of Pinus koraiensis the stereochemistry of neoabienol

  • Published:
Chemistry of Natural Compounds Aims and scope

Summary

1. Neoabienol, isoagatholal, 18-nordehydroabietan-4α-ol, 19-nordehydroabiet-4(18)-ene, and methyl 15-hydroxydehydroabietan-18-oate have been isolated from the oleoresin ofPinus koraiensis Sieb. et Zucc.

2. The trisubstituted double bond of neoabienol has the cis configuration. On thermolysis, cis-abienol rearranges stereospecifically into neoabienol.
