Abstract:
Two practical entries to arylomycin antibiotics core structures are investigated. In route A, the activation of l-Hpg for the key macrolactamization step is achieved in 89% yield in the presence of unprotected phenol and amine functionalities. Alternatively, a propanephosphonic acid anhydride (T3P)-promoted coupling between thel-Tyr and l-Ala moieties in route B led to a facile macrolactamization in 68% yield with a marked reduction in competing oligomerization.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
