Rj. Young et al., BETA-ANOMER SELECTIVITY IN 2'-DEOXYNUCLEOSIDE SYNTHESIS - A NOVEL-APPROACH USING AN ACYL CARBAMATE DIRECTING GROUP, Tetrahedron letters, 35(46), 1994, pp. 8687-8690
Glycosylation of silylated pyrimidines using a phenyl benzoyl)carbamoy
l-1-thio-D-erythro-pentofuranoside yielded 2-deoxy-beta-ribonucleoside
s in good yields with excellent anomeric selectivity. This prototype 3
-O-carbamate directing group was readily formed and removed in high yi
elds.
