An Improved Method for the Application of the 4‐Methoxybenzyl Group to Protect the 2′‐Hydroxyl Group in the Ribonucleotide Synthesis by TFA‐acidolysisThe cleavage of the 4‐methoxybenzyl group from the 2′‐OH‐position of ribonucleosides by the hydrogenation with different Pd‐catalysts as well as trifluoracetic acid has been studied in detail. During hydrogenation, side reactions at the base residue of cytidine‐occurred which, however, could be extensively suppressed by PdCl2catalysis. More practicable results were obtained with trifluoracetic acid in the presence of cation scavengers, allowing smoothly to convert a series of 2′‐methoxybenzyl ribonucleotides to the homogeneou
