Starting from a zamoranic acid derivative (Methyl 15-tetrahydropiranyloxy-7-labden-17-oate) poligodial and warburganal have been synthesized in several steps with a 55% overall yield and 27% overall yield, respectively.

, p. 1324 - 1325 (1987)
The sesquiterpene (-)-warburganal was prepared from a (1S)-1-methoxycarbonyl-2,5,5,8a-tetramethyldecahydronaphthalene (4) obtained by degradation of commercial glycyrrhetinic acid.
The transformation of levopimaric acid into warburganal
Ayer, William A.,Talamas, Francisco X.
, p. 1675 - 1685 (2007/10/02)
The chiral resin acid levopimaric acid (1), isolated from pine oleoresin, is used as a starting material for the synhesis of (-)-warburganal (2).The synthesis proceeds via the endoperoxide of methyl levopimarate, which after ozonolysis, protection of the
