Total syntheses of (-)-nocardicins A-G: A biogenetic approach

The known nocardicins A-G have been synthesized, several for the first time, having geometric and stereoisomeric purities of a high order. The syntheses proceed through the central intermediacy of tert-butyl (-)-3-aminocardicinate (14), which has been pre

Stereocontrolled syntheses of peptide thioesters containing modified seryl residues as probes of antibiotic biosynthesis

Methods have been developed to synthesize tri- and pentapeptide thioesters containing one or more p-(hydroxyphenyl)glycine (pHPG) residues and l-serine, some where the latter is O-phosphorylated, O-acetylated, or exists as a β-lactam. Selection of orthogo
