New base-labile acyloxymethyl groups were evaluated to protect 2′-OH functions of ribonucleotides for regular RNAsynthesis in order to shorten the deprotection procedure upon ammonia. These same acetalester groups were assessed in 2′-modified proRNA as biolabile 2′-protections removable by cell enzymes to generate parent RNA. Demasking of 2′-modified pro-uridylates was studied in cell extracts.
