A synthetic procedure toward 1,3-diazepane scaffolds of naturalproduct-like complexity was developed for the construction of RNA-directed ligand libraries. A molecular building block was designed that combines the characteristics of RNA-binding natural products, including a high density of hydrogen bond donors and acceptors around a rigid, nonplanar scaffold with straightforward total-synthetic accessibility
