Concise total syntheses of (–)-jorunnamycin A and (–)-jorumycin enabled by asymmetric catalysis .

Journey to Jorumycin.

Jorumycin is a structurally complex, pentacyclic organic compound produced by a marine mollusk. The success of a similar compound, trabectedin, in treating certain types of cancer has focused attention on exploring jorumycin's pharmaceutical properties. Welin et al. developed a succinct route to synthesizing jorumycin and the closely related jorunnamycin A that deliberately diverges from the putative biosynthetic pathway underlying prior chemical syntheses. This route, which hinges on a carefully optimized asymmetric catalytic hydrogenation, can be easily modified to introduce unnatural structural diversity for functional optimization in further drug discovery research.
