, p. 3033 - 3034 (1991)
A convenient preparation of S-(2-cyanoethyl) protected 2'-deoxy-4-thiouridine (5a) and 4-thiouridine (5b) is presented. The S-cyanoethyl protecting group is stable to reagents commonly encountered during the phosphoramidite method of solid-phase oligonucleotide synthesis, and is readily deprotected using concentrated NH4OH at 25°C.
