Total synthesis of gelsemoxonine [PDF]

open access: yesPure and Applied Chemistry, 2011
The first total synthesis of gelsemoxonine has been accomplished. A divinylcyclopropane–cycloheptadiene rearrangement of the highly functionalized substrate successfully assembled the spiro-quaternary carbon center connected to the bicyclic seven-membered core structure.

Total synthesis of palau’amine [PDF]

open access: yesNature Communications, 2015
AbstractPalau’amine has received a great deal of attention in the past two decades as an attractive synthetic target by virtue of its intriguing molecular architecture and significant immunosuppressive activity. Here we report the total synthesis of palau’amine characterized by the construction of an ABDE tetracyclic ring core including a trans-bicylo ...

Total Synthesis of Pyranicin. [PDF]

open access: yesChemInform, 2004
[Reaction: see text] A stereocontrolled convergent synthesis of the annonaceous acetogenin pyranicin (1) is presented. Asymmetric Horner-Wadsworth-Emmons (HWE) reactions were used to access key intermediates. The tetrahydropyran derivative 2 was obtained via an asymmetric desymmetrization of the meso-dialdehyde 6, and the butenolide fragment was ...

Total Synthesis of Aquatolide [PDF]

open access: yesOrganic Letters, 2015
A total synthesis of the sesquiterpene lactone aquatolide has been accomplished. The central step is an intramolecular [2 + 2]-photocycloaddition of an allene onto an α,β-unsaturated δ-lactone. Other key steps are an intramolecular Horner-Wadsworth-Emmons reaction to close the lactone and an intramolecular Mukaiyama-type aldol reaction to cyclize the ...
