Nucleoside derivatives with photolabile protective groups

The invention relates to nucleo-side derivatives with photo-unstable protective groups of the general formula (I) in which R1 is H, NO2, CN, OCH3, halogen, alkyl or alkoxyalkyl with 1 to 4 C atoms, R2 is H, OCH3, R3 is H, F, Cl, Br, NO2 or an aliphatic ac

New photolabile protecting groups in nucleoside and nucleotide chemistry - Synthesis, cleavage mechanisms and applications

New photolabile protecting groups have been found in the 2-(2- nitrophenyl)ethoxycarbonyl and the 2-(2-nitrophenyl)ethylsulfonyl group, respectively. The influence of substituents at the phenyl ring as well as the side-chain has been investigated regarding the photolysis rates on irradiation at 365 mn. β-Branching in the side-chain leads to highly increased rates of photodeprotection. A new type of photocleavage mechanism consisting of a photoinduced β-elimination process is proposed.
