合成与大肠杆菌16S核糖体RNA 3'-末端序列相同或相似的寡核苷酸:通过磷酸三酯中间体制备m-6-2-A-C-C-U-C-C和A-C-C-U-C-m-4-2C

Synthesis of oligonucleotides with sequences identical with or analogous to the 3'-end of 16S ribosomal RNA of Escherichia coli: preparation of m-6-2-A-C-C-U-C-C and A-C-C-U-C-m-4-2C via phosphotriester intermediates.

Abstract

The synthesis of two fully-protected hexanucleotides (11a and 11b) via a phosphotriester approach, which is based on the use of two types of protecting groups for the internucleotide linkages, i.e. one 2,2,2-tribromo-ethyl at the 5'-terminus and four 2-chlorophenyl groups for the remaining linkages, is reported. The hexanucleotides 11a and 11b, assembled via a block-wise two-step phosphotriester method, can be deblocked conveniently to give the two hexamers 12a and 12b containing only 3'leads to5' internucleotide linkages.

摘要

报道了通过磷酸三酯法合成两种完全保护的六核苷酸(11a和11b),该方法基于对核苷酸间连接使用两种保护基团,即5'-末端的一个2,2,2-三溴乙基和其余连接的四个2-氯苯基。通过逐步两步磷酸三酯法组装的六核苷酸11a和11b可以方便地脱保护,得到仅含有3'到5'核苷酸间连接的两种六聚体12a和12b。
