Syntheses and configurational assignments of the diastereomers of the 4-nitrophenyl esters of thymidine 3′-(N-phenyl phosphoramidate) and thymidine 5′-(N-phenyl phosphoramidate)

Abstract The separated diastereomers of 3′-(4-nitrophenyl N-phenyl phosphoramidate)-5′-monomethoxytrityl thymidine and 3′-monomethoxytrityl-5′-(4-nitrophenyl N-phenyl phosphoramidate) thymidine have been prepared and their absolute configurations at phosphorus have been determined.
