Terpenoids Derived from Linalyl Oxide. Part 1. The stereochemistry of the davanones

Abstract

Abstract Natural (+)‐davanone is 6 S ,7 S ,10 R ‐2,6,10‐trimethyl‐7,10‐oxidododeca‐2,11‐dien‐5‐one ( 1 ). Equilibration of davanone with base leads to the four possible isomers, but only a single deuterium atom is exchanged when deuterium oxide is the solvent.
