  Pentenyl ribosides: new reagents for purine nucleoside synthesis

  摘要：

  Protected pent-4-enyl ribosides and deoxyribosides were synthesized as reagents for the preparation of nucleosides and deoxynucleosides. Reaction of pent-4-enyl 2',3',5'-tri-O-benzoyl-D-erythro-pentofuranoside with five nucleobases in the presence of N-iodosuccinimide/trifluoromethanesulfonic acid (NIS/TfOH) produced the N-9-beta-nucleosides in 50-70% yields. Pent-4-enyl-2-deoxy-3',5'-di-O-p-toluyl-alpha-D-erythro-pentofuranoside coupled with 6-chloropurine in the presence of iodonium dicollidine perchlorate (IDCP) to produce a mixture of deoxynucleoside isomers (N-9, N-7, alpha,beta) in 91% yield. Under the same conditions, coupling of 6-chloropurine with pent-4-enyl 2'-deoxy-3',5'-O-(tetraisopropyldisiloxane-1,3-diyl)-D-erythro-pentofuranoside produced only N-9alpha and N-9beta products in 40% total yield. The N-9beta nucleoside was the only product of the reaction of 6-chloropurine with pent-4-enyl 2'-O-benzoyl-3',5'-O-(tetraisopropyldisiloxane-1,3-diyl)-D-erythro-pentofuranoside in the presence of NIS/TfOH. Pent-4-enyl ribosides appear to be useful reagents for the synthesis of ribo- and deoxyribonucleosides under mild (NIS/TfOH) or neutral (IDCP) conditions.

These monomers have been used in machine DNA synthesis to give a set of heptadecanucleotides containing up to three analogue nucleotides.

  The rate constants for the hydrolysis of several 6-substituted 9-(2-deoxy-β-D-erythro-pentofuranosyl)purines and 9-(1-alkoxyethyl) purines have been measured at different concentrations of oxonium ion. The effects that varying the polar nature of the alkoxy group exerts on the hydrolysis of unsubstituted 9-(1-alkoxyethyl) purines are interpreted to indicate that the reaction proceeds by a rate-limiting

  日期：——

  A facile and efficient methodology of the synthesis of 6-(hydroxymethyl)purine derivatives (bases and nucleosides) was developed based on Pd-catalyzed cross-coupling reactions of 6-halopurines or N-protected 2-amino-6-halopurines with (benzoyloxymethyl)zinc iodide followed by deprotection. Regioselective hydroxymethylations of 2,6-dihalopurines were also studied and used for the synthesis of 2-chloro-6-(hydroxymethyl)- or 2,6-bis(hydroxymethyl)purines. The 6-(hydroxymethyl)purine ribonucleoside 5f exerted high cytostatic effect and moderate inhibition of adenosine deaminase, while all the other derivatives were much less effective or entirely inactive.

  基于钯催化的交叉偶联反应，开发出一种简便高效的合成6-(羟甲基)嘌呤衍生物（碱基和核苷）的方法。该方法利用6-卤代嘌呤或N-保护的2-氨基-6-卤代嘌呤与（苯甲氧甲基）锌碘化物进行交叉偶联反应，然后进行去保护。还研究了2,6-二卤代嘌呤的区域选择性羟甲基化反应，并用于合成2-氯-6-(羟甲基)或2,6-双(羟甲基)嘌呤。其中6-(羟甲基)嘌呤核苷5f表现出高的细胞静止效应和适度的腺苷脱氨酶抑制作用，而其他衍生物则效果较弱或完全无效。
