Chemistry of the podocarpaceae—XVI

Tetrahedron, 1968
Abstract Treatment of 6α-bromo-7-oxototaryl acetate (II, R = OAc) with NaHCo 3 /DMSO gives 6α-bromo-7-oxototarol (II, R = OH, 5%), Δ 5 -dehydro-7-oxototaryl acetate (III, R = OAc, 45%), Δ 5 - dehydro-7-oxototarol (III, R = OH, 15%), and by fission of the dA/B ring junction, 7-oxo-5,10-secototara- 5,8,10(20),11,13-penataen-13-ol (IV, R = H, 5%).

Chemistry of the podocarpaceae—VIII

Tetrahedron, 1963
Abstract Macrophyllic acid from the heartwood of Podocarpus macrophyllus has been shown to be the bisditerpenoid dicarboxylic acid (I, R  H) related to podototarin, and its di-O-methyl dimethyl ester synthesized from 16-hydroxytotarol. Podototarin (IV, R  CH3) has been prepared by a one-step enzymatic coupling of (+)-totarol and the coupling ...

Tetrahedron, 1962
Abstract Totarol (I, R = H), 16-hydroxytotarol (I, R = OH), sugiol (II), podocarpic acid (III, R = H), methyl podocarpate (III, R = CH 3 ), pododacric acid, β-sitosterol, and two unidentified compounds, the major one of which has been named podototarin, have been isolated from the heart-wood of Podocarpus totara .

Chemistry of the podocarpaceae—IV

Tetrahedron, 1959
Abstract The extractives of the heartwood of Podocarpus dacrydioides A. Rich. contain the known diterpenoid constituents, podocarpic acid (I, R = H), methyl podocarpate (I, R = CH3), ferruginol (II), Δ9-dehydro-ferruginol (III), sugiol (9-ketoferruginol, IV), xanthoperol (V) (in trace amount) and a new resin acid, C20H28O5, for which the name ...

Chemistry of the podocarpaceae—VII

Tetrahedron, 1963
Abstract Totarol (I,R  CH3), 16-hydroxytotarol (I,R  CH2OH) 16-oxototarol (I,R  CH:O), sugiol, podocarpic acid, and two unidentified compounds have been isolated from the heartwood of Podocarpus hallii. The structure (II, R  H) of podototarin, found in P. totara but not in P.

Chemistry of the podocarpaceae—XIV

Tetrahedron, 1967
Abstract The per-acid oxidation of some phenols and their methyl ethers in the podocarpa-8,11,13-triene series has given both p -benzoquinones and 4-hydroxycyclohexa-2,5-dienones. When reaction mixtures were heterogenous, oxidation also occurred at a Me group remote from the phenolic ring.

First extra-Patagonian record of Podocarpaceae fossil wood in the Upper Cenozoic (Ituzaingó Formation) of Argentina [PDF]

New Zealand Journal of Botany, 2015
The main objective of the present paper is to describe a new genus and species of Podocarpaceae fossil wood from the Upper Cenozoic Ituzaingó Formation, Paraná Basin, Argentina, based on a detailed description of the secondary xylem.
