K. Sujino et H. Sugimura, STEREOCONTROLLED SYNTHESIS OF 3'-ISOMERIC BETA-NUCLEOSIDE BY INTRAMOLECULAR GLYCOSYLATION, Journal of the Chemical Society, Chemical Communications, (22), 1994, pp. 2541-2542
Intramolecular glycosylation of a pyrimidine derivative, which was tem
porarily connected to a 2,3-unsaturated 1-thiopentofuranoside through
an ethereal linkage, led to an unusual 3'-isomeric nucleoside in a ste
reoselective fashion.
