Abstract

... by condensation of the protected H,/3 - halogenated deoxyribose with the silylated base in the presence of HgEr2 and molecular sieves as described earlier by Szabolcs, S&gi and Otvos (3). In this way we could separate the -anomers of 5alkyl-2'-deoxy- uridines in good yields, P RESULTS AND DISCUSSION ... (Fig.3). In this way most of the protected -anoniers precipitated /s Page 4. 71 6 A . Szabolcs, G. Kruppa, J. S6& and L. 6ttk% figure +. I R=# b d C ...
