Natural plant extracts are rich in chemical entities with structural, stereochemical, and functional group diversity and complexity. Here, such privileged extracts were effectively harnessed as synthetic platforms for multiple production of α,α-disubstituted amino acid derivatives through the direct chemical derivatization under the Bucherer–Bergs reaction conditions. The derivatization proceeded...
The direct chemical derivatization of natural plant extracts that would enable the straightforward synthesis of natural plant-like molecules seemed to be far from reality due primarily to the inherently complex chemical property of the extract. After model studies, the envisioned derivatization was realized under the rationally designed Bucherer–Bergs reaction conditions to afford unnatural hydantoin...
