title: Synthesis of N,N-dialkylaniline-2'-deoxyuridine conjugates for DNA-mediated electron transfer studies.
abstract: Syntheses of two analogs of deoxyuridine with N,N-dialkylaniline chromophores are reported. 5-[3-(N-methylphenylamino)propanoyl]-2'-deoxyuridine (1) and 5-[2-(4-N,N-dimethylaminophenyl)ethyl)]-2'-deoxyuridine (2) are prepared by palladium-mediated coupling. Preparation of 2 was facilitated by in situ transient O4-trimethylsilyl protection during alkynylation which suppressed secondary cyclization of the coupling adduct.
