USE OF 2-TERT.-ALKYLIMINO-2-DI-C1-4-ALKYLAMINO-1,3-DI-C1-3-ALKYLPERHYDRO-1,3,2-DIAZAPHOSPHORINE FOR O-SUBSTITUTION REACTIONS OF RIBONUCLEOSIDES

摘要

2-tert.-alkylimino-2-di-C1-4-alkylamino-1,3-di-C1-3-alkylperhydro-1,3,2-diazaphosphorines are suitable for O-substitution of protected ribonucleosides with alkyl, alkenyl or aralalkyl groups in the presence of corresponding group-transfer compounds.
