Clerodane diterpenes of Croton hovarum
Phytochemistry, 1997Abstract A clerodane- and a nor-clerodane-type furano-diterpene were obtained from the methanolic extract of the leaves of Croton hovarum . Structural determinations which were made from spectroscopic data led to 3,12-dioxo-15,16-epoxy-cleroda-13(16), 14-dien-9-al and 3α,4β-dihydroxy-15,16-epoxy-19-nor-12-oxo-cleroda-5(10), 13 13(16),14-triene ...

Stereochemistry of -clerodane diterpenes
Tetrahedron, 1986Abstract To piscicidal solidagolactones [IV, V, VII and VIII (1~4, cis -clerodane diterpenes)] isolated from Solidago altissima , a non-steroidal conformation was assigned on the basis of chemical and physicocheaical evidence. 13C NMR chemical shifts of methyl groups proved useful for determining stereochemistry of the A/B ring ...

Clerodane diterpenes of croton ururucana
Phytochemistry, 1998Abstract Sonderianin and two novel furoclerodane diterpenes with a trans A\B ring junction were obtained from the barks of Croton ururucana . Their structures were elucidated by detailed NMR investigation, and the relative configurations established by NOE experiments. 13 C NMR values for the carbonyls of sonderianin were corrected.
