title: Stereospecific Preparations of P-Stereogenic Phosphonothioates and Phosphonoselenoates.
abstract: P-Stereogenic phosphonothioates and phosphonoselenoates were readily prepared utilizing RP-menthyl phenylphosphite 1 by two methods. The first method used elemental sulfur or selenium to react with 1, followed by alkylation of the intermediates with alkyl halides. The second used 1 to react with disulfide or diselenide. Both methods stereospecifically produced the title compounds in nearly quantitative yields under mild conditions. Stereospecific chalcogenation of the phosphoryl was proposed as the key step in these reactions.
