We disclose the syntheses of (+)‐bromodanicalipin A as well as (±)‐fluorodanicalipin A. The relative configuration and ground‐state conformation in solution of both molecules was secured by J‐based configuration analysis which revealed that these are identical to natural danicalipin A. Furthermore, preliminary toxicological investigations suggest that the adverse effect of danicalipin A may be due
我们公开了(+)-
溴莫尼卡利平A和(±)-
氟丹黄素A的合成。这两种分子在溶液中的相对构型和基态构象均通过基于J的构型分析得到了证实,这表明它们与天然构型相同。丹尼西林A。此外,初步毒理学研究表明,丹尼西林A的不利影响可能是由于卤素的亲脂性所致。
