Spoerle, Joerg,Becker, Hans,Allen, Noris Salazar,Gupta, Mahabir P.
, p. 3043 - 3048 (1991)
Three novel dimeric spiroterpenoids, two C35-terpenoids (eudesmane-fusicoccane) and one C30-terpenoid (eudesmane-aromadendrane) which might be biosynthesized via Diels-Alder like reaction were isolated from the Panamanian liverwort Plagiochila moritziana.The structures were elucidated by extensive NMR studies.Additionally, several known bicyclogermacrane, gymnomitrane, eudesmane, aromadendrane, and secoaromadendrane sesquiterpenoids were found.Key Word Index - Plagiochila moritziana; Hepaticae; dimeric spiroterpenoids; C30- and C35-terpenoids; eudesmane; aromadendrane; fusicoccane; Diels-Alder reaction; thermal decomposition.

A few sesquiterpene lactones and monoterpenes when subjected to microwave irradiation on solid surface undergo facile carbon-carbon double bond migration from from exo- to endo-position.
Synthesis of (+)-Isoalantolactone and (+)-Isoalloalantolactone from (-)-Santonin
Blay, Gonzalo,Cardona, Luz,Garcia, Begona,Pedro, Jose R.,Serrano, Angel
, p. 5265 - 5272 (2007/10/02)
This paper reports on the chemical conversion of (-)-santonin into (+)-isoalantolactone and (+)-isoalloalantolactone involving functionality transfer from C6 to C8, refunctionalization of the ring A and the formation of the α-methylene-8β,12-olide moiety.
SYNTHESIS OF UMBELLIFOLIDE AND THREE NATURAL EUDESMAN-12,8-OLIDES FROM (-)-ARTEMISIN
Marco, J. Alberto,Carda, Miguel
, p. 2523 - 2532 (2007/10/02)
The syntheses of the natural 4,5-secoeudesmanolide 1 (umbellifolide) and the eudesmanolides 2, 3 and 4 are described.The starting materials are synthetic eudesmane derivatives, the preparation of which from (-)-artemisin had been previously reported.
