Roimatacene (1) was isolatedfrom the myxobacterium Cystobacterferrugineus strain CbG35 in a bioactivity‐guided process, by following the antimicrobial activity against Escherichia coli. Since 1 was extremely sensitive to oxygen, a protective isolation and handling protocol was developed, by utilizing the free radical scavenger 4‐ethoxyphenol. The structure of 1 was determined by HRMS, 1D and 2D
