    • The present invention relates to a method which can be used for detecting mutations, in particular single nucleotide polymorphisms in parallel in different nucleotide sequences. The method comprises the procedural steps of hybridizing d(G M eATC) containing single-stranded sample nucleotide sequences with single 10 stranded reference nucleotide sequences, fixing single-stranded reference nucleotide sequences or single-stranded sample nucleotide sequences before or during the hybridization, or heteroduplexes consisting of reference and sample nucleotide sequences after or during the hybridization, on a surface, incubating with mutS, mutL and mutH for the incision of the complementary region of the is d(G Me ATC)-sequence in the reference nucleic acid sequence, if a mismatch is present in the hybridized reference and sample nucleic acid sequences, removing the 3`-ends of the incised reference nucleic acids and incubating with a DNA ploymerase and with labeled esoxynucleotidetriphosphates.

    • The invention relates to an improved method for the production of pentopyranosyl nucleosides, in which a significant improvement and simplification of the method steps described in DE-A-19741715 can be achieved. According to the invention, a migration of the 2' acyl protecting group, from the 2' position to the 3' position of the pentopyranoside can be achieved by the application of a catalyst of formula (IVa) or (IVb), where A = -CH2-, -NR -,R , H, optionally substituted alkyl, cycloalkyl, aryl or aralkyl, D = a group of formula CmH2m-, m = a whole number from 1 to 6, R , R and R independently = H, optionally substituted alkyl, cycloalkyl, aryl or aralkyl, or R and R together represent a -CoH2o- group, where o = a whole number from 2 to 4 and R = a NR R group, where R and R independently = H, optionally substituted alkyl, cycloalkyl, aryl or aralkyl.
