Stereospecific Dehydrative Alkylation of Bis-Sulfones: Synthesis of a Lesser Tea Tortrix Pheromone

Article abstract of DOI:10.1021/jo00074a010

The intra- and intermolecular condensation of alcohols with bis-sulfone methylenes, i.e., dehydrative alkylation, using DEAD and Ph3P proceeds stereospecifically at room temperature under essentially neutral conditions affording good to excellent yields o
