Synthesis of aromatic diterpenes synthesis of 12-hydroxy-abieta-8,11,13-trien-3,7-dione

Model studies involving cationic cyclisation of suitable dienes have provided a synthesis of the title compound. Preparation of the dienes from available aromatic starting materials and the modification of the cyclised products are described.

Approach to the synthesis of candelabrone and synthesis of 3,7-diketo-12-hydroxyabieta-8,11,13-triene

An approach to the synthesis of aromatic diterpenes was tested for its generality.Phenylacetonitriles with increasing substitution on the aromatic ring were prepared and alkylated with geranyl bromide and the resulting dienes subjected to cationic cycliza
