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.

Podocarpic acid (1) and totarol (2) have been converted into five diterpenoids reported to have been isolated from the Neem tree.The synthetic diterpenoids have been compared with the naturally occurring diterpenoids but only the structure of nimbidiol (23) has been confirmed.The structure for margosolone, which was reported as (19), has been revised to (20) after synthesis of both (19) and (20).
