The isolation, structure elucidation, and synthesis of antalid (1), a novel secondary metabolite from Polyangium sp., is described herein. The structure elucidation of 1 was performed with the aid of mass spectrometry, high field NMR experiments, and crystal structure analysis. The absolute configuration of antalid was confirmed through the Mosher ester method and ultimately by total synthesis. In
本文描述了Antalid(1)的分离,结构阐明和合成,Antalid(1)是一种来自Polyangium sp。的新型次生代谢产物。的结构说明1用质谱法,高场NMR实验,以及晶体结构分析的帮助下执行。通过Mosher酯法,并最终通过全合成,确认了Antalid的绝对构型。另外,通过对其生物合成基因簇的计算机分析,揭示了该杂种PKS-NRPS天然产物的生物合成来源。
