1.  Dynamic Kinetic Resolution During a Vinylogous Payne Rearrangement: A Concise Synthesis of the Polar Pharmacophoric Subunit of (+)-Scyphostatin 
Organic letters  2010;12(1):52-55.
The diastereomeric epoxycyclohexenols 3a/b (obtained via a Wharton rearrangement of a bis-epoxycyclohexanone precursor) were shown to undergo interconversion via a facile vinylogous Payne rearrangement. Mechanistic issues were probed; the doubly O-deuterated analogs underwent this equilibration more slowly than the parent dihydroxy compounds. It was possible to kinetically resolve the mixture of 3a/b under equilibrating conditions by use of Amano PS. This DKR is additionally noteworthy because it sets four stereocenters in a single event.

2.  Okundoperoxide, A Bicyclic Cyclofarnesylsesquiterpene Endoperoxide from Scleria striatinux with Antiplasmodial Activity 
Journal of natural products  2009;72(2):280-283.
Okundoperoxide (1) was isolated by bioassay-guided fractionation of extracts from Scleria striatinux (syn. S. striatonux) (Cyperaceae). The compound contains a cyclic endoperoxide structural moiety and possesses moderate antimalarial activity.
