(+)-Podocarpic Acid as Chiral Template in the Synthesis of Aphidicolane, Stemodane and Stemarane Diterpenoids †.
In this review the synthetic work in the field of aphidicolane, stemodane and stemarane diterpenoids, in which readily available (+)-podocarpic acid (4) was used as chiral template for the construction of their polycyclic structures, is described as it developed along the years. In the frame of this work (+)-podocarpic acid (4) was a very useful tool in a model study leading to the syntheses of...
متن کاملNitrogen-Containing Diterpenoids, Sesquiterpenoids, and Nor-Diterpenoids from Cespitularia taeniata
Two new nitrogen-containing verticillene diterpenoids, cespilamides A and B (1 and 2), three new nitrogen-containing sesquiterpenoids, cespilamides C-E (3-5), and five new norverticillene and verticillene diterpenoids, cespitaenins A-E (6-10), were isolated from the Taiwanese soft coral Cespitularia taeniata. Compound 1 possesses an unusual oxazo ring system at C-10 while compound 2 displays an...

متن کاملDiterpenes from Erythroxylum barbatum
Das raízes de Erythroxylum barbatum foram isolados dois novos diterpenos entrosan-1ona-5α,15ξ,16-triol (1) e ent-11α-acetoxi-devadarano-15ξ,16-diol (2), além do ent-devadarano15ξ,16-diol (erythroxidiol X, 3) e do procesterol. Investigação do lenho do caule forneceu o ent-devadarano-11α,15ξ,16-triol (erythroxitriol Q, 4), o ent-devadarano-7β,15ξ,16-triol (hidroxidevadarool, 5), o β-sitosterol e ...
متن کاملEight new diterpenoids and two new nor-diterpenoids from the stems of Croton cascarilloides.
From the stems of Croton cascarilloides, eight new diterpenoids, named crotocascarins A-H (1-8), having a crotofolane skeleton were isolated along with two new nor-diterpenoids (9 and 10), named crotocascarins α and β, derived through rearrangement of the crotofolane skeleton. The structures of these compounds were elucidated by means of extensive one- and two-dimensional NMR spectroscopic anal...
