Abstract
The use of 1-[3-O-(2-cyanoethyl-N,N-diisopropylphosphor amidityl)propyl]ferrocene and 1-[3-O-dimethoxytrityl propyl]-1′-[3′-O-(2-cyanoethyl-N,N-diisopropylphosphoramidityl) propyl] ferrocene as reactive synthons for DNA/RNA synthesizer allows to generate ferrocene-labelled oligonucleotides with remarkable DNA detection properties. A new type of di-functionalized ferrocene is used directly as reactive synthons for DNA/RNA synthesizer to elaborate electronic DNA probes.
