title: Aryl nucleoside H-phosphonates as a tool for investigation of stereospecificity during coupling.
abstract: It was found that in stereoselective condensations of ribonucleoside 3'-H-phosphonates with alcohols, the major diastereomer of the produced H-phosphonate diesters is formed from the minor diastereomer of the intermediate phosphonic-pivalic anhydride.
