Synthesis of novel glycopeptidomimetics via Nβ-protected-amino alkyl isonitrile based Ugi 4C reaction

The Ugi-4C reaction employing Nβ-protected-amino alkyl isonitrile, amino acid ester, aldehyde, and glycosyl acid has resulted in novel glycosylated peptidomimetics. The extension of MCR products for the synthesis of N,N′-orthogonally protected glycosylated peptidomimetics has also been demonstrated.
