In this Letter we describe a 12% overall yield synthesis of a model for homoallylic oxygenated α-methylene-γ-butyrolactones with relative stereochemistry defined by selective hydrogenation with Rh/Al2O3. The synthesis was realized in 9 steps involving simple reactions. © 2008 Elsevier Ltd. All rights reserved.
