New, simple, synthetic routes for the preparation of novel glycopeptide antibiotics are described. The structures of the synthesized compounds are elucidated by IR, two-dimensional NMR spectroscopy, and mass spectrometry. The stability of the new glycopeptide derivatives 10a,b is confirmed by assessing the physical character, HOMO-LUMO gap energy, ESP, and the corresponding correlation of 2D-NMR analysis. Furtherly, the target precursors are investigated via the DFT/B3LYP/6–311(G) basis set.
