In order to validate the structure of a rarely reported naturally occurring nucleoside isolated from the broth of Penicillium sp. (NO. 64), practical syntheses of 2′-O-methyl-β-l-arabinosyluridine, 2′-O-methyl-α-l-arabinosyluridine, and 2′-O-methyl-β-l-uridine were accomplished. Comparing their nuclear magnetic resonance (NMR) spectra and physical data, its structure was reassigned as 2′-O-methyl-β-l-uridine instead of former reported 2′-O-methyl-β-l-arabinosyluridine.

2' - O-甲基-β-1-阿拉伯糖基尿苷的全合成并从青霉菌属sp中重新分配核苷。作为2'- O-甲基-β-1-尿苷

为了验证从青霉素sp的肉汤中分离出的鲜有报道的天然存在的核苷的结构。（第64），2'-的实用合成ø -甲基- β-升-arabinosyluridine，2'- ø -甲基- α-升-arabinosyluridine，和2'- ö甲基- β-升尿苷被完成。比较其核磁共振（NMR）光谱和物理数据，将其结构重新分配为2' - O-甲基-β - 1-尿苷，而不是先前报道的2' - O-甲基-β - 1-阿拉伯糖基尿苷。
