The β-anomer of N6-benzyladenosine has been long known as an artificial cytokinin.1) Recently, however, this compound was isolated from a cytokinin-autotrophic cell culture of anise, Pimpinella anisum L.2) Thus, this compound now constitutes the third member of the naturally-occurring cytokinins possessing an N6-benzyladenine structure, together with N6-(O-hydroxybenzyl)adenosine isolated from leaves of Poplus robusta3) and N6-(o-hy-droxybenzyl)-2-methylthio-9-β-d-glucofuranosyl-adenine isolated from fruits of Zantedeschia aethio-pica.4) No information has been available concerning whether or not the a-anomer of N6-benzyladenosine possesses cytokinin activity.We report here the synthesis and cytokinin activity of N6-benzyl-α-adenosine (N6-benzyl-9-α-d-ribofuranosyl adenine).
长期以来,N6-苄基腺苷的 β-异构体一直被认为是一种人工细胞分裂素。1)然而,最近从八角茴香(Pimpinella anisum L.)的细胞分裂素自养细胞培养物中分离出了这种化合物。)因此,该化合物现在是天然存在的具有 N6-苄基腺嘌呤结构的细胞分裂素中的第三个成员,另外两个成员分别是从 Poplus robusta 的叶子中分离出来的 N6-(O-羟基苄基)腺苷3) 和从 Zantedeschia aethio-pica 的果实中分离出来的 N6-(o-hy-droxybenzyl)-2-甲硫基-9-β-d-呋喃葡萄糖基腺嘌呤4。我们在此报告 N6-苄基-α-腺苷(N6-苄基-9-α-d-呋喃核糖基腺嘌呤)的合成和细胞分裂素活性。)
