  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.

  [reaction: see text] Carbohydrates and nucleosides containing a phosphate at the less-hindered primary hydroxyl group are often prepared using a protection/deprotection strategy. Herein we report that the phosphoramidite method can be used to selectively incorporate phosphorus at the primary hydroxyl group of O-unprotected carbohydrates and nucleosides; in situ oxidation of the resulting phosphite
