This paper reports the straightforward enantioselective synthesis of (+)-ancistrofuran starting from a readily available enantiopure buildingblock. A stereofacial directed diastereoselective addition of an organocerate for the installation of the required stereogenic center served as the key step. In addition, the efficientconversion of an intermediate hydroxy aldehyde to the one-carbon homologated
