Haslinger, E.,Michl, G.
, p. 5751 - 5754 (1988)
A new stereoselective synthesis of (+)-taxodione (1) from (-)-abietic acid (2) via the iron carbonyl complex 3 is described.

experimental part, p. 818 - 824 (2010/09/05)
Natural catechol, quinone and quinone methide diterpenes with abietane (15-deoxyfuerstione, taxodione) and totarane (dispermone, 12,13-dihydroxy-8,11, 13-totaratriene-6-one), and podocarpane (nimbidiol, deoxynimbidiol) skeletons were synthesized using ortho-oxidation of phenol with meta-chlorobenzoyl peroxide. Minimum inhibitory activities of these diterpenes and previously synthesized natural diterpenes were measured against methicillin-resistant Staphylococcus aureus (MRSA) and Propionibacterium acnes, which cause serious skin infection associated with acne. Abietaquinone methide and 8,11,13-totaratriene-12,13-diol showed potent activities against S. aureus (MRSA) and P. acnes, and no serious toxicity by oral dose to mice.

Variously oxidized 12 natural abietanes, 6,7-dehydroferruginol methyl ether (3), ferruginol (5), 11-hydroxy-12-oxo-7,9(11),13-abietatriene (7), royleanone (9), demethyl cryptojaponol (12), salvinolone (14), sugiol methyl ether (16), sugiol (17), 5,6-dehyd
Synthesis of (+)-Taxodione
Haslinger, Ernst,Michl, Guenter
, p. 677 - 686 (2007/10/02)
A stereoselective synthesis of (+)-taxodione (1) starting from (-)-abietic acid (2) via the ironcarbonyl complex 4 is described.Conversion of the carboxyl function of 4 into a methyl group via 5 and 6 proceeds in excellent overall yield.The next steps are the introduction of oxygen functions in the positions 12 and 6.Oxidation with BSA yields the quinonemethide 1.The 1H- and 13C-NMR resonances of all compounds have been assigned.
