Figure Presented. A protecting group free and biomimetic total synthesis of (+)-ainsliadimer A has been accomplished in 14 steps from α-santonin. The synthesis relies on a hydrogen bonding promoted [4 + 2]-hetero-Diels-Alder dimerization to afford the key homodimer intermediate, which demonstrates the feasibility of using nonenzymatic conditions to achieve the proposed biosynthesis.
Regio- and stereoselective oxyfunctionalization at C-1 and C-5 in sesquiterpene guaianolides
Bargues, Victoria,Blay, Gonzalo,Cardona, Luz,Garcia, Begona,Pedro, Jose R.
, p. 1845 - 1852 (2007/10/03)
The regio- and stereoselective functionalization at C-1 and C-5 positions in a guaiane skeleton by allylic hydroxylation are described. The stereochemistry of the resulting compounds are identical to those of the majority of natural 1- and 5-hydroxy-guaianolides.
Syntheses of Four Possible Diastereoisomers of Bohlmann's Structure of Isoepoxyestafiatin. The Stereochemical Assignment of Isoepoxyestafiatin

The stereochemistry of isoepoxyestafiatin was determined to be 1β,10β:3α,4α-diepoxyguaia-11(13)-eno-12,6α-lactone by the syntheses of the four possible diastereoisomers 23-26.
