Synthesis. 47:1922-1936
Results from efforts aimed at the synthesis of polyhydroxylated jatropha-5,12-dienes are unveiled. An apparently pre-qualified plot consisting of successive aldol addition and ring-closing metathesis was pursued in order to construct the fully oxidiz

We report the scalable synthesis of a common cyclopentanoid building block for 15-hydroxyjatropha-5,12- and -6(17),11-dienes in 11 steps. Key to the synthesis is an uncatalyzed intramolecular carbonyl ene (ICE) reaction of an e,ζ-unsaturated α-keto

The total synthesis of (-)-ecklonialactone B as well as the 9,10-dihydro derivative by two different strategies is reported. The catalytic asymmetric Claisen rearrangement of Gosteli-type allyl vinyl ethers delivered elaborated α-keto ester building

The enantioselective synthesis of (−)-9,10-dihydroecklonialactone B is described. The catalytic asymmetric Claisen rearrangement of a Gosteli-type allyl vinyl ether was utilized to afford an acyclic α-keto ester building block endowed with functio
