## Abstract The new protecting groups **1a**,**b** and **2a**,**b** were developed for the 5′‐OH group of deoxynucleosides by utilizing the unique characters of the sulfenate and sulfenamide linkage. These new protecting groups have a 2‐(hydroxymethyl)benzoyl or 2‐[(methylamino)methyl]benzoyl skele
