The present invention relates to nucleoside derivatives having photolabile protective groups of general formula (I)in whichR<1>=H, NO2, CN, OCH3, halogen, an alkyl, alkoxy or alkoxyalkyl residue having 1 to 4 C atoms or an optionally substituted aryl residue or an aliphatic acyl residue having 2 to 5 atoms,R<2>=H, NO2, CN, OCH3, halogen, an alkyl, alkoxy or alkoxyalkyl residue having 1 to 4 C atoms or an optionally substituted aryl residue or an aliphatic acyl residue having 2 to 5 atoms,R<3>=H, halogen, NO2, CN, OCH3, an alkyl, alkoxy or alkoxyalkyl residue having 1 to 4 C atoms or an optionally substituted aryl residue or aliphatic acyl residue having 2 to 5 C atoms,R<4>=H, halogen, NO2, CN, OCH3, an alkyl, alkoxy, or alkoxyalkyl residue having 1 to 4 C atoms or an optionally substituted aryl residue or aliphatic acyl residue having 2 to 5 atoms,R<5>=H, dimethoxytrityl or a protective group common in the chemistry of nucleotides or a functional group common for the production of oligonucleotides,R<6>=H, OH, halogen, or PsiR<8>, wherein Psi=O or S and R<8>=alkyl or alkoxyalkyl having 1 to 4 C atoms or an optionally substituted aryl residue or an aliphatic acyl residue having 2 to 5 atoms and a protective group common in the chemistry of nucleotides,R<7>=H, NO2, CN, OCH3, halogen, an alkyl, alkoxy or alkoxyalkyl residue having 1 to 4 C atoms or an optionally substituted aryl residue or aliphatic acyl residue having 2 to 5 atoms,n =0 or 1,X =SO2, OCO, OCS,B=H, adenine, cytosine, guanine, thymine, uracil, 2,6-diaminopurine-9-yl, hypoxanthine-9-yl, 5-methylcytosine-1-yl, 5-amino-4-imidazole carboxylic acid-1-yl or 5-amino-4-imidazole carboxylic acid amide-3-yl, wherein in case B=adenine, cytosine or guanine the primary amino function optionally has a temporary or permanent protective group and/or thymine or uracil optionally has a permanent protective group at the O4 position.The invention also relates to a method of producing these nucleosides, their use and nucleic acid chips built up therefrom.
