5-Hydroxymethylcytosine ((5-HOMe)dC) was recently discovered as the sixth base in the mammalian genome. The development of a new phosphoramidite building block is reported, which allows efficient synthesis of (5-HOMe)dC containing DNA. Key steps of the synthesis are a palladium-catalyzed formylation and the simultaneous protection of a hydroxyl and amino group as a cyclic carbamate. DNA synthesis is possible under standard conditions, and deprotection can be carried out with dilute NaOH.
