A simple, straightforward strategy for the synthesis of polyheterocyclic compounds (PHCs) is reported, which involves iterative cycles of palladium-catalyzed Sonogashira coupling, followed by iodocyclization using I2 or ICl. A variety of heterocyclic units, including benzofurans, benzothiophenes, indoles, and isocoumarins, can be …

Protein glycosylation is the most complex post-translational process. More than 50% of human proteins are glycosylated. The effect of glycosylation on the structure and function of this class of biomolecules is, however, largely unknown and remains to be investigated. Shown on the cover is a glycosylated ribonuclease prepared by a combination of chemical and enzymatic methods to address this ...
