The asymmetric total synthesis of (+)-prelactone B, a biologically important natural beta-hydroxy-delta-lactone derivative that contains a 2,3-trans-dialkylpyran ring system, is described. This approach involves the use of a very efficient oxazolidinone-mediated anti-aldol reaction, and a diastereoselective coupling between a ketene silyl acetal with an aldehyde followed by lactonization.
