With the help of chemical shifts computed with density functional theory (DFT), it is demonstrated that the reported experimental C NMR data of acremolin C are incompatible with the claimed structure of an ,3-ethenoguanine with an isopropyl group at C-1'. An alternative structure, which is in agreement with both experimental and computed data, presents an isopropyl group at the C-2' position of an ,3-ethenoguanine and leads to the conclusion that acremolin C is identical with acremolin B.
借助密度泛函理论（DFT）计算的化学位移，证明了报道的 acremolin C 的实验 13C NMR 数据与 C-1'位异丙基的,3-乙烯鸟嘌呤的宣称结构不相符。另一种结构与实验和计算数据都相符，它在,3-乙烯鸟嘌呤的 C-2'位有一个异丙基，由此得出 acremolin C 与 acremolin B 相同的结论。
