[reaction: see text] The synthesis of 2'-deoxycytidine nucleosides bearing amino and thiol groups appended to the 5-position of the nucleobase via a butynyl linker is described. The corresponding triphosphates were then synthesized from the nucleoside and incorporated into oligonucleotides by Vent (exo(-)) DNA polymerase. The ability of Vent (exo(-)) polymerase to amplify oligonucleotides containing
[反应:见正文]描述了带有氨基和硫醇基的2'-脱氧胞苷核苷的合成,该核苷通过丁炔基连接基附加到核碱基的5位。然后从核苷合成相应的三磷酸酯,并通过Vent(exo(-))DNA聚合酶掺入寡核苷酸。对于氨基官能化的衍生物,证明了Vent(exo(-))聚合酶在聚合酶链反应(PCR)中扩增包含这些官能化胞苷衍生物的寡核苷酸的能力。
