Practical synthesis of 4′-selenopurine nucleosides by combining chlorinated purines and ‘armed’ 4-selenosugar

The synthesis of a variety of chemically modified oligonucleotides requires the development of a practical synthetic method for its building block, i.e., nucleoside analogs. The one-pot Pummerer-like reaction using hypervalent iodine in combination with 6-chloropurine and an ‘armed’ 4-selenosugar bearing an electron-donating group at the 2-position gave the desired 4′-seleno-6-chloropurine derivative in higher yield as compared to the previous method using a ‘disarmed’ 4-selenosugar bearing an electron-withdrawing group at the 2-position. In addition, the use of 2,6-dichloropurine as a nucleobase transformable into guanine skeleton enabled an effective Pummerer-like reaction followed by isomerization to the desired N9 isomer under the acidic conditions. This Pummerer-like reaction between chlorinated purine bases and an ‘armed’ 4-selenosugar is advantageous because it affords 4′-selenopurine nucleosides in one-pot without the need for isolation of the unstable selenoxide derivative.

New RNA purine building blocks, 4'-selenopurine nucleosides: First synthesis and unusual mixture of sugar puckerings

Writer's blocks: The first synthesis of RNA purine building blocks, 4'-selenoadenosine and 4'-selenoguanosine was achieved from D-ribose by regioisomeric rearrangement, which was confirmed by X-ray crystallography. 4'-Selenoadenosine exists in an unusual mixture of north and south conformers in the solid state.

Stereoselective synthesis and conformational study of novel 2′,3′-didehydro-2′,3′-dideoxy-4′-selenonucleosides

(Chemical Equation Presented) Stereoselective synthesis of novel 2′,3′-didehydro-2′,3′-dideoxy-4′- selenonucleosides (4′-seleno-d4Ns) 4a-c was accomplished via 4′-selenoribofuranosyl pyrimidines 11a-c, as key intermediates. 4′-Selenoribofuranosyl pyrimidi
