title: The effective synthesis of uridylyl/3'-5'/5-methylcytidylyl/3'-5'/guanosine.
abstract: The triester method was adapted to the synthesis of uridylyl/3'-5'/5-methylcytidylyl/3'-5'/guanosine. As the protecting groups 4-methoxy-5,6-dihydro-2H-pyran for 2'-OH and 5'-OH groups of uridine and 2'-OH group of 5-methylcytidine, methoxymethylidene for I:3'-cis-diol system of guanosine, and benzoyl for the amino groups of 5-methylcytidine and guanosine were used. The obtained product was characterised by UV, electrophoresis, chromatography, an enzymatic digestion and alkaline hydrolysis.
