  2'-Deoxyisoinosine: Synthesis of a Highly Fluorescent Nucleoside and Its Incorporation into Oligonucleotides

  摘要：

  The synthesis of 2'-deoxyisoinosine (2a) and the related 2',3'-dideoxynucleosides 2b and 3 is reported. The 3'-phosphonate 4b as well as the phosphoramidite 4c were prepared and employed in solid-phase oligonucleotide synthesis.

  [GRAPHICS]The Vorbruggen glycosylation reaction was adapted into a one-step 5 min/130 degrees C microwave assisted reaction. Triethanolamine in acetontrile containing 2% water was determined to be optimal for the neutralization of trimethylsilyl triflate allowing for direct MPLC purification of the reaction mixture. When coupled with a NH3/methanol deprotection reaction, a high-throughput method of nucleoside library synthesis was enabled. The method was demonstrated by examining the ribosylation of 48 nitrogen containing heteroaromatic bases that included 25 purines, four pyrazolopyrimidines, two 8-azapurines, one 2-azapurine, two imidazopyridines, two benzimidazoles, three imidazoles, three 1,2,4-triazoles, two pyrimidines, two 3-deazapyrimidines, one quinazolinedione, and one alloxazine. Of these, 32 yielded single regioisomer products, and six resulted in separable mixtures. Seven examples provided inseparable regioisomer mixtures of -two to three compounds (16 nucleosides), and three examples failed to yield isolable products. For the 45 single isomers isolated, the average two-step overall yield +/- SD was 26 +/- 16%, and the average purity +/- SD was 95 +/- 6%. A total of 58 different nucleosides were prepared of which 15 had not previously been accessed directly from glycosylation/deprotection of a readily available base.
• 6-Chloroxanthosine, a Useful Intermediate for the Efficient Syntheses of [6-¹⁵N]-Isoguanosine, Isoinosine and Other Purine Nucleoside Analogues

  6-Chloroxanthosine 1, when activated towards nucleophilic displacement at the 6-C position by conversion into the corresponding 3-N-(2,4-dinitrophenyl) derivative 4, reacted with aq. (NH3)-N-15 to afford [6-N-15]-isoguanosine 3b in 81% overall yield. Catalytic hydrogenation (Pd/C) of 1 led in 60% yield to isoinosine 8; alternatively, this could be obtained in 88% overall yield through alkaline hydrolysis of triphenylphosphonium salt 6, synthesized from 1 by reaction with PPh(3). The reactivity of 1 was further explored by treating it with primary and secondary amines: the 6-N propylamino and the 6-N piperidinyl derivatives (5a and 5b, respectively) could thus both be prepared in more than 90% yield.
