Significance

Crisamicin A, isolated from the bacterium Micromonospora purpureochromogenes, showed some activity against B16 mouse murine melanoma cells, herpes simplex and vesicular stomatis viruses. The focal steps of the synthesis are: (1) Pd-catalyzed carbonylative lactonization (A + CO → B) and (2) Pd-catalyzed ­homocoupling of H to give the biaryl J.
