The streptolidine lactam is an amino acid constituent of streptothricin antibiotics, which inhibit protein synthesis by targeting the bacterial ribosome but suffer from toxicity as a result of the basicity of the aminoimidazole scaffold in the natural products. On the basis of the streptolidinestructure, we designed and synthesized oxazole analogs with six- and seven-membered lactam rings as building

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
