An efficient template-directed photoligation of oligodeoxynucleotide (ODN) using 7-deaza-2′-deoxyadenosine derivative VZA is described. When ODN containing VZA at the 5′ end was photoirradiated with ODNs containing a pyrimidine base at the 3′ end in the presence of template ODN, rapid and efficient ligation (cycloaddition reaction) was observed without any byproduct formation. ODNs containing VZA showed
使用7-脱氮-2'-脱氧腺苷衍生的寡脱氧核苷酸的有效模板指导photoligation(ODN)VZ甲进行说明。在存在模板ODN的情况下,在5'端含有VZ A的ODN用在3'端含有嘧啶碱基的ODN进行光辐照时,观察到快速有效的连接(环加成反应),而没有任何副产物形成。与以前的光连接反应相比,含有VZ A的ODN显示出极高的反应活性。
