Disclosed are heterocyclic scaffolds useful, for example, for solid-phase organic synthesis of combinatorial libraries and methods for the preparation thereof. Also disclosed are libraries, including combinatorial libraries, and methods for preparation thereof. Exemplified are the following scaffolds (I):
Synthesis of orthogonally protected optically pure ketopiperazine, diketopiperazine, ketodiazepane, and 3-aminopyrrolidone building blocks for peptidomimetic combinatorial chemistry
convenient synthesis of orthogonallyprotected multi-tethered, optically pure 2-ketopiperazine, diketopiperazine, 2-ketodiazepane and 3-aminopyrrolidone scaffolds for Fmoc combinatorialchemistry has been developed. It utilizes accessible chiral amino acid precursors, sequentially applying reductive alkylation, dipeptide coupling and regioselective ring formation as key steps. These scaffolds are expansion
