Efficient synthesis of 5-hydroxymethyl pyrimidines and their nucleosides using microwave irradiation

Abdel-Rahman, Adel A.-H.,El Ashry, El Sayed H.

, p. 2043 - 2044 (2007/10/03)

Hydroxymethylation of uracil (1), cytosine (3), 5-hydroxymethyl-2′,3′-O-isopropylideneuridine (5), 5′-O-tert-butyldiphenylsilyl-2′,3′-O-isopropylideneuridine (7), 2′,3′-O-isopropylidenecytidine (9) and 2′,3′-O-isopropylidene-5′-O-tritylcytidine (11) was efficiently carried out with paraformaldehyde in alkaline medium under microwave irradiation in very high yield.
