Natural amino acids were converted to the corresponding allylic alcohols A, from which key precursors C were obtained via a three-step sequence [(a) Ac2O/Py or CbzOSu/Et3N/DMAP; (b) NMO/NaIO4/OsO4(cat.); (c) Ph3P = CR2CO2Bn]. The allylic alcohols D were further transformed to the desired pseudodipeptides I through the corresponding bromo derivatives E via a reductive deconjugation process.
