Totalsynthesis of HirsutelloneB has been achieved by a convergent synthetic strategy. This synthesis features direct construction of the highly strained 13-membered macrocycle of HirsutelloneB utilizing the Ullmann-type reaction. To the best of our knowledge, this is the first application of macrocyclization utilizing an intramolecular Ullmann-type reaction between an aliphatic alcohol and aryl

Leading the way: The synthesis of natural products with new biological targets is one of the driving forces for the development of new antibiotics. The synthesis of the two secondary metabolites corallopyronin and myxopyronin (see picture) have been achieved, which are prominent leads for the inhibition of bacterial RNA polymerase.
