C. Crestini et al., DIMETHYLDIOXIRANE OXIDATIONS - A NEW AND EFFICIENT DESULFURIZATION OFTHIOPYRIMIDINE AND THIOPURINE NUCLEOSIDES, Tetrahedron letters, 34(48), 1993, pp. 7785-7788
Dimethyldioxirane reacts with 2', 3', 5'-tri-O-acetyl-4(3H)thiouridine
1 and hio-9-(2',3',5'-tri-O-acetyl-beta-D-ribosyl)purine 2 to afford
several interesting desulfurized products.
