Application of rhodium(II)‐catalyzed intermolecular nitrene transfers to naturally‐occurring guaianolide compounds led to isolating nine new derivatives that possess an amino functional group at C‐1, C‐2, C‐10, C‐11, and/or C‐13 positions. The relevance of a late‐stage C−H amination strategy in medicinal chemistry is demonstrated by the improved antiproliferative activity of the C‐2 aminated analogs
